Johannes Witt 2fb69afde6 Add GraphEdit.is_node_hover_valid(...) method ...

This is a virtual method that can be used to add additional error
condition checks while the connection is still being dragged. If true is
returned, the connection is valid. If false is returned, the connection
is invalid and thus not possible (ie. it will not snap). The virtual
method is exposed with an underscore to scripts.
