- added else branch to conditional actions

- 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
