Weekly bug summary report

[Daniel Berlin]

I ported gnome's weekly bug summary report to Bugzilla 2.17.3 for use 
in GCC's bugzilla.

See http://gcc.gnu.org/bugzilla/weekly-bug-summary.cgi


Anyone else interested in it?
If so, i'll throw it in a bug at bugzilla.mozilla.org

Be forewarned, however, that it generates it's own html (though the 
queries it uses to determine counts and whatnot are nicely encapsulated 
in weekly-summary-utils.pl), and i can't see an easy way to templatize 
it.

I also rewrote the queries so they are about 10-100x faster than the 
ones the gnome version uses (see 
http://bugzilla.gnome.org/weekly-bug-summary.cgi for an example as to 
how slow the ones they use are). Had the same problem regenerate mode 
of collectstats.pl originally did (to_days on every record).
