* scales are now saved sensibly instead of just being dumped as is (also, tables have now constrains)
* added admin=weight-presets to edit presets
* added an internal user on id:0 who 'owns' the wt-presets and the +1 rates on new comments
* consequently added constraints to comment-related tables
Misc:
* Util::toJSON() priorizes its flags over CFG_DEBUG, wich fixes the modelviewer-redButton
* moved terrible javascript-dump from admin-page to template
* fixed typo preventing management of custom weight scales
* added forgotten GET-Parameter to sanitization, preventing rating of comments
* avoid hardcoding locales
* do not show tooltip on BUTTON_WOWHEAD
* separated into appropriate subclasses
* unified sanitizing of $_GET and $_POST data using build in filter_input()
* index now always tries to resolve page calls with ajaxHandler first and as a page last
