Test stubbing package.

[Arcath]

I'm repeating myself in a few packages with my stubbings which isn't really necessary.

If we create @open-screeps\tests-stub it could provide:

• All the constants
• A selection of creeps e.g:
  • creep1 which has:
    • fatigue: 1
    • carry.energy: 100
    • carry.power: 200
    • body....
    • spawning: true
    • move() alwayrs returns ERR_TIRED
  • etc....
• A selection of Rooms
• A copy of functions that dont use storage e.g. getLinearDistance

It would then be usable by players to do testing in their own AI and us in open-screeps packages.

I don't think a predefined selection of rooms and room objects (like creeps) is a good idea, as tests might want to check for different environments. Simple functions to create proper instances of them sounds like a good idea though. I'm going to give this another thought and come back with some ideas.
