automatically added to the set of languages to be built and installed
unless they are explicitly added to the set of disabled translations.
This eliminates the need to manually add a lang to the Makefile when a
new translation is submitted (svn add will still be necessary).
creates a tarball i(and specfile) similar to 'make tarball' except that
it uses svn export to pull the latest committed version rather than the
currently contents of the tree (as make tarball does). This is to make
pristine checkins to SUSE's autobuild system and the openSUSE
buildservice easier.
