Alpha 0.0.2 - Genetics rework

Additions

• The game loop has now limited the user input queries to 60fps to avoid too frequent queries that eat CPU cycles for breakfast.
• A random AI that will select a random (but valid!) action with a random (but valid!) target at each turn.
• For developmers: unit tests for genetics and random AI.

Changes

• The action and genetics modules are reworked and tightly integrated.
• Using and extending both has been made much easier and intuitive.
• Monster generation organisation has been tightened up
• Various parts of the software architecture have been refactored and cleaned up to be easier to read.

Removed

• A whole layer of indirection for mapping genetic traits to actions and attributes has been removed

Fixes

• Plenty of bugs in genetics, DNA encoding and decoding

Known issues

• Attacking actions are in the game but don't do anything yet
