K8 Bugs + Potential Framerate Fix

[GhylTarvoke]

1. When K8 torched a door for the first time, it swam in circles, swam through the door, then torched the door again from the other side. I went in and flushed the airlock, leaving K8 suspended in midair. A moment later, it vanished.

2. After killing K8 and putting its chip in the Omnitool, I noticed that hovering my cursor over K8's empty compartment still gave me a "this thing can be picked up" icon. Clicking it caused Simon to obtain a second chip, which could be put in the Omnitool to trigger the Catherine conversation all over again.

3. I tried turning off vertical sync and AA, with minimal framerate improvement. Then I used the NoSteam .exe, and my framerate improved significantly. Weird.
