If user tries to use a locale that their system doesn't fully support,

even though our language MO files are installed, it will switch to C
locale (which is not UTF-8), and the language won't be used in Tux Paint.
Utilizing hack designed by Albert that sets LC_ALL to an arbitrary,
working UTF-8 locale (currently using en_US.UTF-8), and then setting
the LANGUAGE env. var.  Seems to work!  (I can use Fula (ff_SN.UTF-8)
on my Ubuntu 9.04 system that doesn't have Fula support.)
