Updating core text area autosizing library.
Introduced textarea autosizing functionality to missing areas of forum, such as on profile and in the dashboard, by including query.autosize.min.js file. The entire forum should now automatically resize all textareas. Made sure that the JS for loading this functionality is all in one place (global.js).
Removed livequery dependency for loading textarea autosizing. Using pertinent events for binding functionality instead. Updated gdn.autosize wrapper to more intelligently decide when to attach and when to trigger a resize.
