Changed turbogears to use packages installed via easy_install... in
the virtualenv rather than system-wide packages.
Moved the bulk of the upload log code into the helperlib.
Made the map tiler look for existing copies of a map tile to avoid
doing redundant work.
Made the map tiler kill stalled wesnoth clients (they typically stall
because an uploaded map uses custom tiles).
Updated URL handling to correctly send out a 404 for nonexistent URLs
instead of a 501.
Updated killview backend to support multiple datatables instead of one
hardcoded one (now supports GAMES,GAMES_AI,GAMES_MP, any other GAMES*
table).
Updated URL references in the html templates to stats.wesnoth.org
instead of wesnoth.org/wesstats.
Added a title to graph view pages.
Increased size of pie graphs.
Changed log type to RotatingFileHandler and changed logging file to
/var/tmp/wesstats.log. Added support for multiple tables, although
still broken and incomplete. Refactored some long string catenations
into a cleaner style.
...split controllers into seperate files, created a separate file to
hold helper functions, updated TODO, updated html template to show
'None' for used filters when no filters are used
