* moved wt_presets to DB
* 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
