function added to store selections from packagechooserq
line 103 in Config.cpp needs adjusting to restore working regular widget based packagechooser
prettyStatus added, made visible in packagechooserq only, ViewStep not altered in packagechooser for this yet
When the module is loaded and the viewstep created, it doesn't have a
module Id **yet**. That is set after reading more of the configuration
file. It **is** set by the time setConfigurationMap() is called,
so pass it on to the Config object then. This means that packagechooser
modules can skip the *id* config key and use the module Id.
Rip out most of the ViewStep that deals with configuration,
move it to a Config object (not one that supports QML yet,
though), and massage the model a little.
