[PATCH] Add ability to detect and fix identical ways in validator

[anonymous]

There are mistakes, when uploading something partially fails and someone uploads it again. As a result, there are two (or sometimes even more) identical ways - sometimes the way references identical nodes, sometimes both identical ways have their own nodes, but at exact same positions. It could be useful, if validator will be able to detect identical (identical = exactly same set of tags + exactly same position of all nodes) ways with button to fix this (delete all but the first (lowest ID) way)
