Version 1.413 HOTFIX FOR 2017.2 - 16 october 2017
- Fixed naming conflict after Unity introduced a class that had an identical name to a class in RealtimeCSG

WARNING: 2017.2 has a bug where upgrading a Unity 5.4 scene file/prefab will break your Realtime-CSG scene!
         You can work around this by loading and saving your scene files & prefabs in 5.5, 5.6 or 2017.1 before you load it in 2017.2

- Fixed issue with not being able to extrude surfaces
- Fixed issue with (accidentally) calling GameObjectUtility.SetStaticEditorFlags every frame would make it impossible to rename objects?

- Known Issue: the experimental brush "Contents" part is temporarily removed from this version since it's currently broken, 
				it'll be brought back (in some form or another) in a subsequent version.
Version 1.412 - 22 july 2017
- Rendering the visible parts of a model is now optional and can be changed in the bottom right corner of the scene view
