Option to toggle "Semi-Lock" and "Collision" on/off

[Gambler423]

I would really love to see the option to tick/untick "Semi-Lock" in the right-click menu.

Some of the objects in a mod i'm working on, only work with semi-lock turned off, but the game the objects are used in is best played with semi-lock on... so it would be nice to exclude those objects from the global semi-lock state on a per-object basis.

(Sorry for the double thread title, I can't seem to edit it)
