Im glad to hear from you, Damjan, as i truly admire all the hard work you put
on winemenubuilder... i've been studing its source code, and its a phenomenal
tool.

The issue is not about associations within windows. Its about the bridge that
winemenubuilder does in native associations. More precisely, functions
build_native_mime_types() and freedesktop_mime_type_for_extension(). They 
should also lowercase native extensions.

Currently, if a windows app registers .z (or .Z, or .amr), winemenubuilder will
not find the corresponding native mimetypes application/x-compress (or
audio/AMR), and it **will think those extensions dont exist in native
system!*** and will create new, redundant mimetypes for them.

Not only that, but the new mimetypes and .desktop entries will not work the way
they should: native apps will not be able to open .Z files, because
x-wine-extension-z.desktop wont handle them

winemenubuilder is a bridge between windows and native. So it should force
lowercase for all incoming extensions (meaning build_native_mime_types() should
lowercase fd.o entries when building the list) for truly case-insensitiveness
to work correctly. And it should use proper case when creating .desktop and
mime.xml files in native system.
