[WIP] Polishing

It's almost done. It just needs a few tests. What I did do:

- Unpluginned it, just a normal PHP package now.
- Added namespaces
- Added PSR-4 autoloading
- Typos and docblocks
- 50% of a test.

I've taken the liberty to add this to a FOC namespace instead of Jippi if that's alright. Anyway, it will be done tomorrow. I'll leave Travis up to you.
