Feature Request - Load line colors from connections

[ekrichbaum]

Current:
Connection id 15, source 8, targe 6, srcIfName Te2/3 tgtIfName xe-0/2/0 color is blue (along with everything)

Desired:
Connection id 15, source 8, targe 6, srcIfName Te2/3 tgtIfName xe-0/2/0 color uses color from connection (or defaults to blue)
