 This patch adds a SELECT box underneath the main editing window for the
 Theme and Plugin Editors that lists functions used in the current file
 (PHP files only). If you select a function from the list and click the
 "Lookup" button, it launches a new window that uses the new documentation
 API to load the appropriate page for that function.

 Includes: Native PHP functions, All user-space functions used in the
 current file (except those specifically excluded)

 Excludes: any classes/functions defined in the current file (since it
 assumes they are plugin/theme-specific and therefore won't have
 documentation available via the docs API),

 Allows users to filter the list of function names to "ignore" via the new
 'documentation_ignore_functions' filter.

 The way tokenizer works is a bit funky, so please keep an eye out for
 things being included in the list that shouldn't be there and let me know
 so I can clean them up. Could use some testing by loading various
 plugin/theme files.
