Added, Draw Ellipse mode: added "Angle" parameter. Can be used to rotate the shape.

Changed, Draw Ellipse mode: lowered minimum subdivisions to 3.
Fixed, Browse Action and Browse Effect windows: first option was always selected for any generalized action/effect parameter during generalized action/effect setup.
