Get rid of implicit "top names"
For some models, implicit "top names" are taken from file name and not explicitly part of filter names.
This causes problems when top names are made explicit. It seems top names are made explicit by creating a subsystem, moving everything into it, and perhaps setting some kind of topname parameter on it.
Daniel suggests running every filter file through a script to make top names explicit. Make the RCG only use explicit top names.
