[Done for V0.36] New action for spells

[L!ghthouse]

I would like to create a new spell that will temporarily raise the strength in my entire party. I suggest adding a new action ACTION_BOOSTALL_BYOBJECT. I could then link this to a KU Potion, which would raise all of my party's strength temporarily.

Or is there another way to do this?

No I don't think there's another way of doing this, so I've implemented your suggestion for V0.36.

Whilst I was at it, I've also added party versions of the two heal methods which act in the same way.
