Bug fix:
1. text speed is doubled.
2. HQ does send now 2 collectors for free.
3. towers doesn't shoot anymore if you are in build mode.
The 2 collectors from the HQ works in the editor but not in the build. It seems to be related to the "Start" function in the collectors. In Start it was looking for the HQ itself and potential targets. As the HQ wasn't available yet (althrough the collectors were a child of the HQ), the route couldn't be determined. The "Start" function was executing earlier then needed. This has been fixed by starting a coroutine with a second delay ;-).
