Did some bugzilla cleanups

[Michael Schwendt]

Status update here:

* Scripts seem to work just fine with rpmfusion after a bit of cut'n'paste
reorganisation (for easier testing). Used them to sync a change in livna's
bz. Cannot test creating/updating comps in rpmf bz because of lack of
write-access, of course. Official RPM Fusion "Product"s don't exist
in bz yet either.

* Found four owners.list files for four different fedora/epel rpmfusion
flavours. Need to cover this with a config file or options, as not
just the download location for those files is different, the bugzilla
product ids are different, too ("Fedora" vs. "Fedora EPEL").

* Bugzilla products for "free" and "nonfree" are the same. Intentional?

* owners.epel.list.free is incomplete:
