This sript refreshes all GET queries. Because of that some tests had to be modified. And api resposnes are reproducible now (sets results are changed to a "sorted" set, so with every query we should have the same response).
Second big change is that overlay iamages are stored differently (there are no overlays in submaps anymore)

info message about restricted access improved (there is a difference when you are guest or logged user)

every map has optional default center coordinates where map should be focused after first open during session

when plugin is unregistered check about removing listeners is added and all listeners are removed by force if necessary
