Untested implementation of TileSides
changed some IDE settings to import the RubySDK, manage gems, and stub out the file loader.

Added loader tests that prove we can serialize to file and back for the ship tiles. Need to do tile maps, now.
Propagating validation methods to ShipTile class
a bit of cleanup of the loader spec, along with stuuuubs!

Start implementing the cards, aswell as stub out calls on Shipinstance that we'll need
