Upcoming grapple selection changes (Patreon)

Going to change how grapple moves selection are performed. Currently it is done via a dir key + grab button. In the future, pressing the grab key will open up a special "pick a move" menu. While this menu is open, the game is paused and the player can pick and choose a desired move to perform on the opponent.

The motivation for the change are as follows:

• Allows for a variable number of moves per character (>4)
• More flexibility in presenting to the player the moves they are able to perform based on the circumstances. Eg. when opponent is futa, when you have an rope/potion item in the inventory, etc.
• A nice descriptive box so moves are no longer forced into the 4 categories and can have special individual properties.
