Initial progress towards converting auto-completion framework to Spry. Not currently in a very working state.

Fixed SQL syntax error thrown during rank data fetch

Fixed access type warning in discussion button generation in template

Fixed: init_vars double-init check ignored theme changes/reloads

Made template parser remember last initted page_id and namespace to avoid double init; made additional_headers reassign only do so if $template->additional_headers is empty (it's being blanked somehow, need to come up with a backtrace sometime)

Fixed undefined index left over from scope system rewrite a few days ago

Fixed two bugs in paginator: noisy warning when rows run out and empty strings not being treated as valid from formatting functions

Fixed title not being set properly in redirect()

Renamed some functions (that were new in this release anyway) due to compatibility broken with PunBB bridge

Moved some TinyMCE init code to make JS early init work
