[Bug]: Beam offsets work opposite of cone offsets

[kwvanderlinde]

Describe the Bug

When a cone light has an offset, it measures counterclockwise from the token facing. But a beam light measures its offset clockwise from the token facing.

To Reproduce

1. Add these lights to a campaign:

   Beam: beam width=1 offset=90 10#ff0000
   Cone: cone arc=15 offset=90 10#ff0000
   

2. Add two token to the map. Equip one with the Beam, the other with the Cone light.
3. Set the token's to have the same facing.
4. See the lights go in different directions.

Expected Behaviour

offset should have the same meaning for beams as for cones.

Just discovered that they do agree on isometric grids. All other grids appear to have the issue.
