tAuthentication

[bearbin]

OK, my update is done. It allows for easy translation of tAuthentication into different languages, and individual languages per player. All translators have to do is to follow the example of english.lua and make their own language file.

I have a few more features I want to add, but I have also done considerable code cleanup and I want to release this version

Note: Treat this as unstable, MCS is not compiling on Linux ATM so I can't test it.
