This is the second proper update! This one fixes a bunch of annoying bugs, apart from the scenarios. They still don't work.
Here's the changes:

• Added an update checker
• Rewrote plugin.yml, so now the version gets incremented! Before, it was stuck on 2.0.1 because I forgot to change it in the main class. Big sad.
• Added an update checker so when these embarrassing things happen you can be annoyed until you update!
• Rewrote scenarios system. It still doesn't work. Sorry.
