Hotfix -- Dec 1

Fixed a few bugs:

• Beans in the inventory panel now draw with shapes properly when in colorblind mode.

• Hitting [Enter] while in a puzzle no longer brings up the menu, toggles the grid, and resets the puzzle all at once (these were all unintended).

• Removed an unnecessary bean from "panopticon".

• Removed two unintended solutions from "cave-in".
