Make "on" syntax mandatory for value sources and interceptors

Where you would have written

   x: NumberAnimation {}
   y: Behavior {}

you now must write

   NumberAnimation on x {}
   Behavior on y {}

This change also makes the parser more strict with respect to multiple
assignments to a single property - they're no longer allowed.  For example
this

   x: 10
   x: 11

is now an error.
