#9 Change the way object actions are handled
In FARSA 1.x the actions of an object must be slots and their name is the name of the function. Moreover they are not automatically added to the Actions menu and only the actions of the Component are added. It should be possible to have actions in every configured object (reachable using the path to the configuration group) and actions should be automatically added to the menu. The BaseExperiment class already solves some of these issues (in principle it could be possible to remove the necessity that actions must be slots with minimal source changes). A related problem is in which thread created objects live. For the moment they are created in the GUI thread but often run in a separate thread, perhaps also reation should be moved to separate thread (being careful with Widget creation)
