This release is mainly bugfixes, but includes some changes to the endboss to reduce the ways you can kill it in a "boring but safe" way. There are probably still more ways I don't know about, please go find them. :)

CHANGES:
- Endboss is significantly harder now ... don't fly too far away

FIXES:
- Couldn't beat the boss in co-op if one player was dead
- Aerolab menu fixed in co-op
- Flak bullet collider changed so that it won't pass through objects in its initial stage
- Fixed visual glitch where a part of the endboss would weirdly follow it around
- Custom missions were still playing the old alpha music
- "P", "B", and "I" keys are no longer hardcoded for various functions
- Fixed a few building descriptions
- Fixed cash exploit when going from the carrier menu to the title menu
- Subtle AI aiming bug fixed, it was using the wrong time delta, it may be slightly more accurate now
