Fixed being able to go back to c1m3_factory from c1m2_hub01.
Removed batteries with lower energy value in c1m3_factory tollbooth tutorial.
Added a sequence that hints how to say 'Can you give me that' in c1m2_hub01.
The door to the beer quest alien will now open only after you have visited the tollbooth in c1m2_hub01.
Fixed hlss_electricwall working incorrectly and letting items and characters through sometimes.
Fixed a case where in the Transistor Battery tutorial you could get stuck if you used the grenade on the camera or any breakable prop. You can still get stuck if you use the grenade on any hostile NPCs. Fix for this will come later.
