MGG: New Monster select screen (Patreon)

This is one of the new big changes I wanted to show off. Still a bit of a work in progress, but mostly complete; the new Monster select screen makes it much clearer for players which of their monsters they're about to style, train, sell, etc.

Previously, only owned and available monsters were displayed. Every monster in the Garden is now displayed, unowned or busy Monsters are greyed out, and the reason is displayed on their panel. I will add checkboxes to let you filter some monsters out, as well.

I'd like to add a few small buttons to the panels to allow players to stop interactions, for example, but so far bailing on actions mid-way seems to cause problems. I'll see what I can do about that before the upcoming release.
