Why did I do this

Added a bunch of stuff for ship class, created subclasses for a bunch of
ship components, created enum for ship types.
Added fuel calculations to travel

Now calculate how much fuel you would use to travel, only travel if you
can, then subtracts required amount based on distance and efficiency.
Added hull stuffs

Added hull, damage, and buttons to deal damage / repair hull.
Menu on startup

Also, need to resize window to show new ship panel stuffs.
