changes from 0.4.10 to 0.4.11:
Thanks for Silly_Warlock for the first two improvements listed below!
- added a for-each-force loop instead of specific forces, during init routine to set up each force
- added a handleOnScriptRaisedBuilt function for script-spawned entity event handling.
- adding migration file to help players who add mod after starting game to auto detect existing techs and unlock recipes properly for them.
