Fixed focus of AJAX login form fields in IE; removed stale/unused call to $template->makeParserText() in paginate_array(); added hook page_create_request to possibly help control creation of pages of certain namespaces from plugins; fixed critical bug in user CP that prevented plugins from adding custom CP modules

/**
* JavaScriptCompressor class,
* removes comments or pack JavaScript source[s] code.
* ______________________________________________________________
* JavaScriptCompressor (just 2 public methods)
* |
* |________ getClean(jsSource:mixed):string
* | returns one or more JavaScript code without comments,
* | by default removes some spaces too
* |
* |________ getPacked(jsSource:mixed):string
* returns one or more JavaScript code packed,
* using getClean and obfuscating output
* --------------------------------------------------------------
* Note about $jsSource input varible:
* this var should be a string (i.e. $jsSource = file_get_contents("myFile.js");)
* should be an array of strings (i.e. array(file_get_contents("1.js"), file_get_contents("2.js"), ... ))
* should be an array with 1 or 2 keys:
* (i.e. array('code'=>file_get_contents("mySource.js")))
* (i.e. array('code'=>file_get_contents("mySource.js"), 'name'=>'mySource'))
* ... and should be an array of arrays created with theese rules
* array(
* file_get_contents("secret.js"),
* array('code'=>$anotherJS),
* array('code'=>$myJSapplication, 'name'=>'JSApplication V 1.0')
* )
*
* The name used on dedicated key, will be write on parsed source header
* --------------------------------------------------------------
* Note about returned strings:
* Your browser should wrap very long strings, then don't use
* cut and paste from your browser, save output into your database or directly
* in a file or print them only inside <script> and </script> tags
* --------------------------------------------------------------
* Note about parser performance:
* With pure PHP embed code this class should be slow and not really safe
* for your server performance then don't parse JavaScript runtime for each
* file you need and create some "parsed" caching system
* (at least while i've not created a compiled version of theese class functions).
* Here there's a caching system example: http://www.phpclasses.org/browse/package/3158.html
* --------------------------------------------------------------
* Note about JavaScript packed compatibility:
* To be sure about compatibility include before every script JSL Library:
* http://www.devpro.it/JSL/
* JSL library add some features for old or buggy browsers, one of
* those functions is String.replace with function as second argument,
* used by JavaScript generated packed code to rebuild original code.
*
* Remember that KDE 3.5, Safari and IE5 will not work correctly with packed version
* if you'll not include JSL.
* --------------------------------------------------------------
* @Compatibility >= PHP 4
* @Author Andrea Giammarchi
* @see http://www.devpro.it/
* @since 2006/05/31
* @since 2006/08/01 [requires SourceMap.class.php to parse source faster and better (dojo.js.uncompressed.js file (211Kb) successfull cleaned or packed)]
* @version 0.8
* Dependencies:
* Server: BaseConvert.class.php
* Server: SourceMap.class.php
* Client: JSL.js (http://www.devpro.it/JSL/)
* Convertion is supported by every browser with JSL Library (FF 1+ Opera 8+ and IE5.5+ are supported without JSL too)

/**
* SourceMap class,
* reads a generic language source code and returns its map.
* ______________________________________________________________
* The SourceMap goals is to create a map of a generic script/program language.
* The getMap method returns an array/list of arrays/dictionary/objects
* of source map using delimeters variable to map correctly:
* - multi line comments
* - single line comments
* - double quoted strings
* - single quoted strings
* - pure code
* - everything else (for example regexp [/re/] with javascript), just adding a correct delimeter
* --------------------------------------------------------------
* What about the delimeter
* It's an array/list of arrays/dictionary/obects with some properties to find what you're looking for.
*
* parameters are:
* - name, the name of the delimeter (i.e. "doublequote")
* - start, one or mode chars to find as start delimeter (i.e. " for double quoted string)
* - end, one or mode chars to find as end delimeter (i.e. " for double quoted string) [end should be an array/list too]
*
* optional parameters are:
* - noslash, if true find the end of the delimeter only if last char is not slashed (i.e. "string\"test" find " after test)
* - match, if choosed language has regexp, verify if string from start to end matches used regexp (i.e. /^\/[^\n\r]+\/$/ for JavaScript regexp)
*
* If end parameter is an array, match and noslash are not supported (i.e. ["\n", "\r"] for end delimeter of a single line comment)
* --------------------------------------------------------------
* What about SourceMap usage
* It should be a good solution to create sintax highlighter, parser,
* verifier or some other source code parsing procedure
* --------------------------------------------------------------
* What about SourceMap performance script/languages
* I've created different version of this class to test each script/program language performance too.
* Python with or without Psyco is actually the faster parser.
* However with this PHP version this class has mapped "dojo.js.uncompressed.js" file (about 211Kb) in less than 0.5 second.
* Test has been done with embed class and PHP as module, any accelerator was used for this PHP test.
