Fixes bug #77565: We listen to the Composer's loginstatechanged event and show and hide the tool.
Fixes #77562: We now get the locality name from the logged user authority. Aslo fixed a minor bug which prevented showing the tool in reloads.
Minor fixes for when the user was logged and then unlogged with the tool open.
We hide/cancel the tool if the user unlogs.
Replaced polygon style with Borde_comuna, as the first appears to no longer exist.
Added custom overview map that allows keeping a fixed view.
