Fixed merge conflicts

Clean up of simulation version, the number that rules the compatibility of teleports:
- It's not configurable anymore, it's fixed in code. Each number means an increase in features of the teleport procedure
- Its definition moved to the global VersionInfo class
As of now it's still 0.3.
