Added "Braai", similar to "Coffee"

This is my first ever pull request on a project, so forgive if I have done something horribly wrong.  

I added `class Braai` as a copy of `Coffee` with just modified messages.  It was a feature request from #ubuntu-za on freenode.

Have a look at the help module, and play with it a bit.
