Patch #22 complete.

# 6.12.
Your savefile is now also deleted when you abort an exploration mission by exiting to the main menu.
Fixed several texture alignment/wrapping errors.
The background no longer jumps when you switch game modes.
There is now a visual effect when your ship is invulnerable.
Changed the subspace drive: The acceleration is now higher and your ship becomes invulnerable for a second after activating it. Awesome :)
