First working localization
This is enough to get the localization working when running straight from git. The translation files are not yet being installed by setup.py so packaged versions of fdroidserver won't include them yet. There doesn't seem to be a simple way to include them, just lots of varying hacks.
To run this yourself, do:
$ cd /path/to/fdroidserver $ make -C locale $ LANGUAGE=zh_Hans ./fdroid update -h $ ls locale # to see the available languages
