Some more minor tweaks, along with a few bug fixes.

- Fixed a bug where walking past a healing building would open the heal UI even without interacting with the building.

- Fixed a bug (I think...) where enemy cooldowns were being randomly reset, causing enemies to attack faster, or even attack twice at the same time.

- Fixed a bug where mousing over an enemy while switching stages would cause its info panel to get stuck on the screen

- Created a button template to be used for all buttons in the game. Haven't actually added this template across all buttons yet, but yeah.

- Removed one of the old resolution settings and added a new one, as one of the old ones was causing scaling problems.
