Some Idevices may require extra config information beyond what is in exe.engine.config. e.g. Wikipedia iDevice has a list of Media Wiki sites to access.
The user should have some way of setting this config data and saving it. BUT it shouldn't be hardcoded into the eXe engine Idevices are meant to be modular.
Could be saved in exe.conf?
but need some way to display config settings in preferences dialog.
Could be utterly generic with a definition of config fields and field types
Or do we just ignore modularity and hardcode Wikipedia options?
