[Wizard] [Frost Orb] Add half-charged LMB

Currently it feels very very bad to do half charged LMBs on accident which might be mainly caused by this:

It would be good for the gameplay and the look and feel of the frost orb if there would be a half charged attack that would do slightly more damage then a tap attack, take one block pip (and maybe applies a slight snare). As of now if you let go a nearly fully charged LMB you basically did a tap attack which means:

• low damage

• no block pip damage

• wasted time for charging

The frost orb does not have any block so any time that you waste or any shot that you let go that doesnt slow the enemy or reduce his block can kill you.
