Touch up events

[NBKelly]

I simplified a few events and then got sidetracked, so:

• This changes icons to be static abilities instead of manually adding/removing them
• This also allows for multiple icons to be on a card at once
• If you hover an icon, the source card is outlined in bold red if possible

Closes #8483

There's still a bit to do, and I think some of the other prs added an icon or two, so I'll need to go over this again the hard way before we do a patch.
