1.0.2

fix map sharing

preview

Workaround circular dependency and fix invalid json response.

The share module has a circular dependency with maps, and those should
be separated. Workaround for now will do.

POST response must return a valid json, as we currently handle errors in
a map update (and redirect to login page).

New menus

Improve the node editing dialog to the point where it can be used.

A few tweaks here and there.
