- implemented history for any object extending BaseClass (i.e. almost any)
- added distance() calculation method to base class
- Button "edit JSON" in Action Lists now hidden by default, can be enabled in plan properties
- fixed bugs:
- updating json of DisplayText was not working properly
- log output in Tile.isFreeFor was broken
