Possibility to change used hardware by user

[klues]

With the possibility to set up a control for a given device with different hardware alternatives (see e.g. #135 or #130), a new problem arises:

Problem
In some cases it is no longer possible to automatically decide which hardware the user wants to use. E.g. controlling a "tablelamp" can now be realized with:

• IrTrans + Infrared plug or
• FS20 PC sender + FS20 plug

if both, the IrTrans and FS20 PC sender is installed and connected to the computer, it is no longer automatically decideable if the user wants to set up the control for the lamp with FS20 or IrTrans. A third possibility to control a tablelamp would be IrTrans + Infrared light bulb.

So both cases/problems can occur:

1. How to decide which of several connected hardware devices to use for setup? (e.g. IrTrans vs. FS20)
2. Which additional hardware to use for a given installed hardware? (e.g. IrTrans + Infrared plug or IrTrans + Infrared light bulb?)

Solution
I would implement a wizard that suggests a solution by default (like now - e.g. IrTrans + IrPlug for a tablelamp) but with the possibility to change the used hardware afterwards by user selection (e.g. interchange IrTrans with FS20 or IrPlug with IrBulb).
