- Ported , add selected to group (Ctrl-G), remove selected from group(Alt-Ctrl-G)
- add selected now has a add new entry which will put the object into a new group
- remove selected now has an ALL option which removes the object from all groups
- remove code is currently very messy, this will have to do until a better solution arrises, menus return strings instead of numbers perhaps
- add/remove to/from group of active object still need to be done
