Revised mudra system. Help improve/error check

[Gemina]

After putting in some additional thought, and thinking 3 charges of mudras might be too much; I was thinking that max charges are still set at two, and TCJ can reset those charges every 120s. I might update this later.

edit: updated Fuma Shuriken tooltip so that a weaponskill cancels the mudra effect. I'm also thinking about the Ninjutsu button just being Fuma Shuriken by default, and it changes when under a mudra effect.
edit: added the caveat "not available outside combat" to Ninjutsu Ready effect. TCJ update.
