Fixed win32 config saving, keyboard mapping, and AltGr bugs.

Made extensive changes to the launcher to provide more control
over setting up auto-start and it now saves configuration to
the user's documents directory if auto-starting at login and
saves to the system directory if auto-starting at boot.
Replaced MapVirtualKey() with table lookup to work around that
function's lack of support for extended keyboard scan codes.
Added first cut at support for AltGr.
