We want to be able to filter according to Profile as well.
For example: if I have the profile "x86 Fedora Core 3" I would like to
be able to filter my bugs according to this profile.
I should be able to choose more then one profile to filter by so for
example: if I'll choose 4 Profiles to filters bugs for a specific
project - I'll see only the bugs that includes these specific profiles.

This filter should show all filters used in a certain project.
