Make games and trade proposal items allow long text.
Changed overlays so they must be closed by an "X" in the corner instead of tapping anywhere, as "anywhere" kept making fast-pased games irritating to trade and auction during.

All buttons on the BoardView now support long-pressing to view a tooltip of sorts.

Fixed a bug where a Card proposal would actually add a proposal for the corresponding Estate instead.
Fixed Card trade proposals. They now work as intended.

Fixed a bug with estate trade proposals not allowing them to be added.
Fixed the layout of the game list and proposal dialog lists and added some padding.
