Screenshake Carries Over in Map Editor

[Wozenbelt]

I would have recorded this one, but:
(1) There's an issue with recording the map editor where it randomly flashes purple. I know it's not just me; see that really good bug report Quinterball made.
(2) My computer's garbage and can't record above -19 fps.
It seems as though if an explosion occurs at the same time a user exits the map editor's test mode, the screenshake will remain with them. When no buttons are pressed, there is no visible effect, but moving the camera around in edit mode looks shaky and somewhat nauseating. It doesn't go away unless you exit edit mode. The explicit procedure is as follows:
1. Load up the map editor.
2. Enter test mode.
3. Blow something up and exit test mode. You should hear the full explosion noise.
4. Move the camera around and behold.
Unfortunately, the effect doesn't stack.

Recording in the map editor (or the game) is nothing we will support.

Screen shake fixed after Alpha v.1.3.3.
