Categorization of duplicate nodes

[Nakor]

Following with my email on josm-dev, I implemented a change in the validator that categorize duplicate nodes: duplicate highway nodes, duplicate waterway nodes, duplicate railway nodes, ... and mixed duplicate nodes.

This patch is attached.

Note: I can commit it myself if needed but since this is not my plugin I thought I go through trac first.

Looks good, you can apply it yourself!

Generally, you can edit other plugins if the change is clearly an improvement and you are confident it does not break anything. (Or be prepared to fix it when bug reports are coming in. ;) )
