Surecast - Allow Move-&-Casting

[Toodles]

This would make this ability just perfect.

Movement is a cast-interruption too, so it makes sense to the current description.

Could be a trait just for BLM if you're worried about it being OP for healers.

Heck, would curb the FL's nerfs a bit.

Honestly, it wouldn't be horrible for balance either... and would be pretty sweet gameplay-wise.
