First releas of Pirate's Keel version 0.2!

Yarr!

First version of 0.2 is there. Changelog:
- by the popular demand, I added support for keyboard. That required me to overhaul my input method and make it more expendable, but in the end, I'm happy of the final product. Users can change input method in options menu. Few known issues: No look around while using keyboard as yet, and no in-game input help. - I fixed AI bug, that happened when AI got out of bounds of navmesh. Basically, it couldn't find it's way back so it got stuck. I fixed it by giving them a failsafe fallback location they can access whenever they're stuck. I will update my public repo further down the line. Happy Pirating!
