* fixed several deprecation notices and warnings from MySQL8, most notably:
- SQL_CALC_FOUND_ROWS: stopped using DBSimple::selectPage and query 'SELECT COUNT(*) ...' separately where needed
- ON DUPLICATE KEY UPDATE ... VALUES(): use row alias for new values instead of VALUES function
- boolean shorthands to long form (&& -> AND, etc)
* split completion table into it's subcomponents
* this should save some disk space as some keys and null fields have been optimized out and col sizes have been reduced
* sort ICC raid bosses first to last
* prevent direct access to some internal files where applicable and reword error for others
* if CFG_DEBUG is set also enable debug in client javascript
* non-breaking formatting changes
* define regions and missing locales for later use
* Conditions: loot rows initially have no 'id'

* squash multiple notices from error log
* fixed copy&paste error preventing view on custom profiles
* fixed display of spell requirements if mount was required after changs to mount sorting
