Cleaned up converting from source to target. Can we come up with a way to convert with a target type.
Fixed parsing of RelativeSource to accept 'AncestorType={x:Type StackPanel}' or 'AncestorType=StackPanel'.
Monitors list can change during the callback.  We are handling accordingly.
Moved binding tests into separate dir.
Implemented RelativeSourceMode for Binding and EventBinding.
