- added language-update.sh

Script to update the language files, with lots of tricky bash code ;-)

  MUST be run everytime you add a string to en.lang.

      ./language-update.sh --patch
  should do the job, unless something goes wrong.

      ./language-update.sh --help
  prints all available options.

+    Usage:
+
+    '"$0"' [--notext | --patch] [--nocleanup] [foo.lang [bar.lang [...] ] ]
+
+    --notext will only list the translation keys (useful for a quick overview)
+    --patch will patch the language file directly
+    --nocleanup will keep all temp files (for debugging only)
+
+    You can give any number of langugage files as parameter.
+    If no files are given, all *.lang files will be used.
+
+    Note for translators: untranslated entries have a comment
+        # XXX
+    attached.
