[Update] Crawle 0.2.4a --> 0.2.5 file

This is for people who need to manually update their Crawle.

Changelog:
0.2.4a --> 0.2.5
# FIXES
- None necessary.

# CHANGES
- Removed all useless features and code.

It may not look like much, but this makes the game significantly faster. Some of the useless features I've removed are the inventory and lighting engine since we're going to do those in the new engine and do them much better too.
