OK, I'm done with the preg_replace() in the paragraph parser. It's too buggy. Replaced with preg_match_all()/str_replace_once().

/**
* SYNOPSIS OF PLUGIN FRAMEWORK
*
* The new plugin manager is making an alternative approach to managing plugin files by allowing metadata to be embedded in them
* or optionally included from external files. This method is API- and format-compatible with old plugins. The change is being
* made because we believe this will provide greater flexibility within plugin files.
*
* Plugin files can contain one or more specially formatted comment blocks with metadata, language strings, and installation or
* upgrade SQL schemas. For this to work, plugins need to define their version numbers in an Enano-readable and standardized
* format, and we think the best way to do this is with JSON. It is important that plugins define both the current version and
* a list of all past versions, and then have upgrade sections telling which version they go from and which one they go to.
*
* The format for the special comment blocks is:
<code>
/**!blocktype( param1 = "value1"; [ param2 = "value2"; ... ] )**
... block content ...
**!* / (remove that last space)
</code>
* The format inside blocks varies. Metadata and language strings will be in JSON; installation and upgrade schemas will be in
* SQL. You can include an external file into a block using the following syntax inside of a block:
<code>
!include "path/to/file"
</code>
* The file will always be relative to the Enano root. So if your plugin has a language file in ENANO_ROOT/plugins/fooplugin/,
* you would use "plugins/fooplugin/language.json".
*
* The format for plugin metadata is as follows:
<code>
/**!info**
{
"Plugin Name" : "Foo plugin",
"Plugin URI" : "http://fooplugin.enanocms.org/",
"Description" : "Some short descriptive text",
"Author" : "John Doe",
"Version" : "0.1",
"Author URI" : "http://yourdomain.com/",
"Version list" : [ "0.1-alpha1", "0.1-alpha2", "0.1-beta1", "0.1" ]
}
**!* /
</code>
* This is the format for language data:
<code>
/**!language**
{
// each entry at this level should be an ISO-639-1 language code.
eng: {
// from here on in is the standard langauge file format
categories: [ 'meta', 'foo', 'bar' ],
strings: {
meta: {
foo: "Foo strings",
bar: "Bar strings"
},
foo: {
string_name: "string value",
string_name_2: "string value 2"
}
}
}
}
**!* / (once more, remove the space in there)
</code>
* Here is the format for installation schemas:
<code>
/**!install**
CREATE TABLE {{TABLE_PREFIX}}foo_table(
...
)
**!* /
</code>
* And finally, the format for upgrade schemas:
<code>
/**!upgrade from = "0.1-alpha1"; to = "0.1-alpha2"; **
**!* /
</code>
* As a courtesy to your users, we ask that you also include an "uninstall" block that reverses any changes your plugin makes
* to the database upon installation. The syntax is identical to that of the install block.
*
* Remember that upgrades will always be done incrementally, so if the user is upgrading 0.1-alpha2 to 0.1, Enano's plugin
* engine will run the 0.1-alpha2 to 0.1-beta1 upgrader, then the 0.1-beta1 to 0.1 upgrader, going by the versions listed in
* the example metadata block above. As with the standard Enano installer, prefixing a query with '@' will cause it to be
* performed "blindly", e.g. not checked for errors.
*
* All of this information is effective as of Enano 1.1.4.
