The libcolord async API used to use a thread to get the properties for the
device and profiles in the background.
This was racy as hell, and was not good API design. Connect to each device and
profiles explicitly before we access the properties.
This is designed so power users can create virtual devices (just like in
ColorSync) that represent things like 'Hexachrome Press #2' or 'Cinema'.
This new UI isn't actually wired up yet, and there are no new UI controls as
the UI still needs love from the designers.
This was added at this point for two reasons:
1. To get the translations early so we can enable this later
2. To be able to delete the code out of gcm-prefs.c
