Bool for disabling random rotation of "ending" property in beam

[Staplergun]

The ending, and quite likely the start properties in a beam do this random rotation.




A boolean under the 'ending' property in the beam prototype to disable this random rotation/translucency would be quite nice to have. Beams could have further application as forms of pointing to or marking entities in the game world that use a solid marker as it's endpoint.

Okay, added for 0.17. I also added a property to disable the translucency of the end and start animations.
