Methane 3.6.0

Changes:

• Bumped libMCdev version to 1.4.2, which now only includes the core debug parts. (trimming size down a lot)
• Fixed mushroom placement with Methane ON. Instead of guessing using world time, I instead opted for players just being able to place whenever.
• Adds in a few small holdovers from an unimplemented feature of Methane.

No April Fools prank in Methane for now... or is there?
