Fix for negative scaling & Mirror menu in Object mode (CTRL+M)

Browse Source 
Hope Martin likes this simple hack. :)

Also; added flag in constraint to denote whether its local or not. That
way its possible to:

- prevent local scale and rotate on multiple objects to change own position
- draw constraint lines cleaner
