Added an editor test to check all mesh colliders on every prefab in the project for the r/w flag This is going to be a trickier issue to debug now that non r/w meshes are being stripped from the server - in the past they would throw an error on startup which would make it easy to find offending meshes, but now they will just not collide with anything Checks 4095 prefabs, takes about 10 minutes Enabled r/w on 32 meshes, test passes Commit 1/2 because of plastic
