[Bug-gnuzilla] Minor update fixes profile path and missing translations

[Rubén Rodríguez]

I have pushed a small change that fixes a problem with profiles being
stored at ~/.gnu/icecat instead of ~/.mozilla/icecat

I have also reverted a change that made the retrieval of translation
files faster, but prone to failure. This release should have all the
translations that where missing in the previous release.

Version number is 31.5.0-gnu2, files are available at
ftp://ftp.gnu.org/gnu/gnuzilla/31.5.0-gnu2/

Please repackage for distros again.
