Indicate when Another User has Modified an Open File #68
Description
Right now, Director displays a green circle when the file has not been edited since it was opened or saved, and yellow if it has been.
It would be very useful to have another color circle indicating the file has been saved by another user and that on saving the current changes will override that user's changes.
i.e. If I have the file test.txt open, and a friend does as well. They edit and save test.txt while I have it open, so the circle icon gets marked light blue to indicate I will be overriding their changes if I save.
