Build seed node list without duplicates
Build seed node list without duplicates

The random selection of a node shouldn't favor repeats that occur in the
hardcoded and DNS seed node lists.

Remove hardcoded ":18080" address which gives parse error.

Test: bitmonerod --log-level 2

The seed node list displayed at startup shouldn't show duplicate
addresses (includes port).
