Fixed gaze attributes

The attributes for the gaze command should now be the same across
plugins.

Gaze commands require a horizontal and vertical attribute, in which
negative -2 -2 is looking towards the bottom left and 2 2 is looking at
the top right.
Straighten out gaze.
Put back user gaze code.
