Conversion of "Toggle Link" tool to "Make Link"

Browse Source 
This commit alters the behaviour of "Toggle Link" tool found in the node
editor so that it only makes link between selected sockets. Links cannot
be deleted by using the tool again as before. Instead deleting links can
be done by using the old method (drag with lmb).

The delete functionality may require further investigation to see if it
should be improved.
