Show asset moves in sidebar

[zkat]

You can invoke asset moves through the Make a move command, but not the moves sidebar. We should display these, perhaps under an "Assets" category in each ruleset?

Ahh this should be doable now with the changes I made for the character sidebar. Basically, the moves sidebar can now track the active character context, and use that to get all of the moves-- this will match the Make a Move command.

Since these are all character moves, maybe we should put them under a heading with the character's name?
