Fat widgets

[hh]

Thank you very much for that.

This solves the situation where the LC-8 version and the LC-9 version are the
same (have the same lcb file). 
Thus you can only have widgets that use LCB-syntax/features that are present
in both LC-8 and LC-9, especially no new/different LCB features from LC-9.
