More optimization work. Moved special page init functions to common instead of common_post hook. Allowed paths to cache page metadata on filesystem. Phased out the redundancy in $paths->pages that paired a number with every urlname as foreach loops are allowed now (and have been for some time). Fixed missing includes for several functions. Rewrote str_replace_once to be a lot more efficient.
<!-- Stuff related to toolbars and clickable buttons.
The plan was to use this on the toolbar for most pages. Never made it into the release,
but still provided as an otherwise-unused component for plugins to make use of.
