[Bf-python] [Scripts bundle] 2 new scripts : Swap Objects Location and Move to the Symmetric Location

[Campbell Barton]

Hey Jms. I saw your script and suspected this was possible with 
transform. (CVS transform at least)

You can get the same functionality by setting the rotation mode to 
active object. and Enable "Transform object centres only"
-- Then scale by -1

(s)key, (-)Key (1)Key

This is a bit nicer too since it works on more then 1 object. and slows 
you to do other things- only x/y axis for eg.


Another thing, though its find in most situations.
Object.GetSelected()[0] is deprecated, since it iosnt always the active 
object.
Use Scene.GetCurrent().getActiveObject() instead, this is particulaly 
good for finding which object is in edit mode. (Edit mode mesh scripts) 
because an object can not be selected but be in edit mode.
