Add missing calls to Show( false ) to some main frames (Kicad, eeschema, gerbview), to force config saving when closing these windows.
Code cleanup and minor coding style fixes in footprint_wizard_frame.

The desire is to migrate designs *away from* case independence, and to create
designs which use literally (case specific) interpreted component names. But for
backwards compatibility, you may turn OFF this option if you really must.
(Remember that with KiCad using text data files, typically you would be better
off simply doctoring those files into a case literal state with a text editor
and move forward into the brave new world of case specificity. Also, BOM
generators may not work properly when you have this option turned OFF, the xml
export's referential integrity is broken on library part name. Hence the default
is ON now, as of 29-Jan-2014.
