Improvements for the link selection for the Network Map

Browse Source 
Currently the Network Map will draw multiple links between
devices and ports, overlapping themselves on the graph. The
criteria used to select the link is also unspecified.

Instead only allow a single link between any two devices/ports.
Also prefer links with shorter names, and for links derived
using arp/mac, prioritise links with a matching ip address.
