Translation update for Afrikaans & Hungarian

I translated the *preferences* strings, which jonnius added, to Afrikaans and Hungarian, although stuff like *chat* and *micro blogging* doesn't really translate very well.

I also added a link to the issue tracker on GitHub in the `Report-Msgid-Bugs-To` field in the l10n files and put the project name and current version number in their `Project-Id-Version` field.

Lastly, I checked the git log to find the commits where you incremented the version number and [tagged them](http://git-scm.com/book/en/Git-Basics-Tagging) so that they can be referenced more easily. If you accept this pull request you should also get the tags, but if not you can pull them from my repo using

    git pull --tags git@github.com:sinisterstuf/messagingmenu.git

and see them using `git tag -l` as well as in the drop-down box on the GitHub site which you can use to see your repo as it was at a specific version of the project:
