[feature_suggestion] Add Level0 as editor option

[pedjas]

Level0 (http://level0.osmz.ru) is very fast tag editor. It is meant to be used to edit tags only, not geometries so it does not have map as graphical interface.

It is very useful when one needs just to edit some tags. No need to wait for heavy and slow graphical editor to load.

API is very simple: http://level0.osmz.ru/?url=n4630470276 where url contains OSM object ID.

I usually edit existing objects and all I need is to change tags. Lots of time is wasted waiting for ID editor, JOSM or some other editor to load, just to edit or add one or two tags.

The integrated tags editor does not fit the same need ?

Level0 is bit different, and in many cases more useful tool.

Integrated tags editor is limited by editing tag by tag. Level0 has simple free form editor so one can easily cut&paste whole bunch of tags.
