Methane 1.7

Thanks to everyone who downloaded Methane, I never actually expected people to actually use this cursed mod, but here we are!

• Minor changes, mainly being able to change the way that the "Methane is now [x]" is displayed, allowing you to instead have a brief, less "spammy" pop-up instead.

• Small code changes, nothing major yet.

• Fixed a few text inconsistencies.
