Bug 680131: Replace the MPL 1.1 license by the MPL 2.0 one in all files, and add it to files which miss one
r=kiko r=mkanat r=mrbball a=LpSolit

r=mkanat, a=mkanat (module owner)

During the CVS imports into Bzr, there were some inconsistencies introduced
(mostly that files that were deleted in CVS weren't being deleted in Bzr).
So this checkin makes the bzr repo actually consistent with the CVS repo,
including fixing permissions of files.

Bug 537766: Add contrib/console.pl, a script which allows using Perl with Bugzilla libraries in a read-eval-print loop.
