[CopyStack] CopyStack forces lock

[Jon Arnold]

When one starts the CopyStack screenlet, it locks itself everytime the user clicks on it.

Lines 304-306 of the applet look like this:
 def on_mouse_down (self, event):
  self.tooltip.hide()
  self.lock_position = True

So if someone wants to move the screenlet, they will probably go to the options and unlock it. Then when they go to move it, they are unable because the program has locked itself. This is done because the applet can not perform the drop function when it is not locked. The end-user, however, should not have to comment out the lock_position line in the code to be able to move the applet.

The ideal solution, in my opinion, is that the applet would lock itself when the user clicks on the individual "clips" but not on the bottom stack.
