Did some bugzilla cleanups

[Thorsten Leemhuis]

Hi!

Just fyi, I did some cleanups in bugzilla; if I did something wrong yell 
and/or just reopen please.

Some things to note:

- There are a lot of packages awaiting review; see
https://bugzilla.rpmfusion.org/showdependencytree.cgi?id=2&hide_resolved=1
for a list. I suppose those packagers that have packages in the review 
queue try to get review exchanges organized; maybe via the wiki somehow?

- matthias seems to be the default owner for infrastructure bugs; Xavier 
is doing most infr things these days, so that IMHO should be changed; 
who has permissions to do that

- while at it: a lot of packages that are listed in owners.list are not 
in the package list in bugzilla; how to we get that working?
