Define / change BidCos-Address in RM

[teichtaucher]

Describe the solution you'd like

Many people want to migrate from other Homematic implementations. For example I'm using HomeMatic in FHEM. In FHEM it's one of the first steps to define the HM-ID (or so called BidCos-Address of the central).
When I setup RM from scratch the HM ID of the corresponding interface is used intially. It would be nice if this ID could be changed afterwards in the web interface of RM. It can be changed via some workarounds (adapt the id in file /etc/config/ids). But the work is quite high and not possible for unexperianced users.
Once the HM ID is changed, it is quite easy to pair the devices with RM using pair by serial and to use thm (temporarily) in parallel to FHEM or other implementations.
So I'd appreaciate to make the HM ID or BidCos Address configurable in RaspberryMatic.

Describe alternatives you've considered

Change the HM ID via SSH in RaspberryMatic.

Is your feature request related to a problem?

No. It's working also without this feature. But with higher effort for migration.
