Sarjuuk acbe969b8d Setup:
- setup can now be run from CLI. Use "> php index.php --help" to start off
- updated logging for use with CLI
- added generators for client imagery (icons, maps, talents, ect)
DBC:
- parsed DBCs are now expected in the Aowow-DB, prefixed with dbc_* (they are joined with
  these tables, so its easier to have them here altogether)
- setup/db_setup_3.zip may be reapplied (optionally)
- alternatively aowow will now extract you own DBCs alongside your textures.
  They will be parsed and saved to DB, as needed.
Misc:
 * HOST_URL and STATIC_URL will now be determined automaticly once and
 * then saved to ?_config (setup by CLI requires these to be set)
Spell:
 * added glyph-symbol to infobox for glyph-related spells
