* 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)
* append a filemtime timestamp to js/css files to work around browser caching after update
* shuffle script handling around a bit
* also user pages cant have community content
* also fix breadcrumbs on items page
* further optimize search
- use achievement 4496 as shortcut for everything based around total achievement points
- get talent distribution separately
- get total profiler-items found separately
- opt to not sort found results
* fixed Profiles with zero Achievement Points
* added cache key genrator i forgot :<
* fixed typos
* vastly improved input validation
* content and type validation occurs when filter is created
* contextual filters like itemTypes are now only applied in context
* initial implementation
* this includes a complete reindexing of everything touching icons
* this also means, no linking to red-rocket-site though, they index them differently
