r420 - Cutscene Camera Fixes and Redstone Power Fix

Spent some time fixing issues with the camera today as well an old bug with redstone power and doors.  Going to be probably taking a couple day break from coding but will likely whip up some tutorial videos covering of various new features.

• Fixes cutscene camera flipping out with its rotation.
• Fixes camera block freezing at the end.
• Third person camera state remains through activating a camera block.
• Redstone power blocks can now trigger doors properly.
