Config file that allows definition of the default view parameters for:
-- index pages (columns, search args, sorting)
-- item pages (field types, widths, etc)
-- search pages (type of searching)
The actual format of this file will probably be Python, as this is too complex for .ini and I don't want to introduce *another* config file format.
Another idea is to have the templates installed into "share" and used from there if no local template exists. Possibly configure that too (template path).
