Started adding information
Implemented information in xml  for buildings
Information can now be represented in XML format in the factory.
Refactored gamestate
Merge branch 'master' of https://github.com/Tadimsky/vooga into merger
Working but not the way we want...
Factory can add custom producables but buildings do not produce.
Production works finally!
Merge branch 'master' into Add-information-to-factory
