v0.2

Major reworking of the map:

• Added, moved, or deleted Things are now updated in real time
• Ticking Map Camera Angle will now show the level's default camera angle with a yellow arrow
• You can now view and set this angle in the level file using the numerical box directly below it. Accepted values range from 0 - 359

Truncated level files will now be fixed to be the correct length on save. This is needed for levels that are too short to have camera angle info in.
