Hallways 0.8, or: almost done now!

A pretty big update, this game is really nearing "really actually finished" status now.

• Completely redid the level generation. Levels should now be more varied, more challenging and more visually interesting.
• Build in all kinds of checks to ensure all generated levels are now actually completable and to eliminate those pesky out-of-bounds errors.
• Redid the controls to be a lot more user-friendly. No more switching between modes, just click where you want to go.
• Lots of minor bugfixes.'

Still on my to-do:

• Better music.
• An actual endgame.

Stay tuned for more!
