AMIGAOS: Make use of the new drawer icon

On AmigaOS the user can customize every icon including drawers.

This is a customized drawer icon for ScummVM with the original "S"
scaled on top of it.

This icon may change with further revisions of AmigaOS4 (if the
default icon images change).
CGE2: Remove fallback detection for English translation.

WIN32: Create a registerDefaultSettings for WIN32 specific defaults

Instead of having duplicate code where environment settings are read,
do this only once.  Don't create directories when just determining
the defaults, the user may override those.
