Scorching ray should target lock

Story: every league I hope that you have changed scorching ray to target lock since it is hard to aim.

Problem: once you have aimed the ray and let go of the stick, the bounce that occurs will often cause the ray to change direction. Sometimes it will even do a 180 spin.

Solution 1: change the alternate use for channel skills (scorching ray at least) to enable target lock. This way the controller plays best in isometric arpgs.

Solution 2: improve the input "noise filter" and allow messing with deadzone
