Extra frames state API

[felixjones]

Need to review how states are handled for extra frames.

Plugin commands should have the ability to set states for characters, and those command should support some conditions.

• AltimitMovement state this set "fishing" - Plays the fishing animation once
• AltimitMovement state this set "dance" 3 - Loops the dance animation three times
• AltimitMovement state this clear - Clears current state

Plugin manage should also allow configuring of extra frames. Idle state timeout should be a configurable option.

More states to add:

• Jump (jump movement command)
• Idle (character waiting N frames)

The way assets are handled needs to be revised to allow support for "exclude unused assets". Adding named/index character sheets in the Plugin Manager and allowing referencing them by name/index in the XML definitions is a good way to do this.
