ordered bricks somewhat
simple listview-pages now use one shared template (instead of having the same file multiple times)

some bug fixing here and there
 - achievement: faction is no longer out of range (need to reparse the faction :/)
 - item: quality is prepended to the name again and wont be left out in case of heirlooms (is 0)
 - general: forgot to change some error()-calls in index
 - and some more wich i forgot..
implemented generic filters

- what which index does needs to be implemented in the implementation
- differences to wowhead
   * strings in criteria are more lenient and will also work with partial matches
   * the ? and * wildcards are supported
implemented pages:
 - Achievement / Achievements (filtrable)
 - Classes
 - Currencies
 - Itemsets (filtrable)
 - Races
 - Title / Titles
 - Events
