Subject: [PATCH] icon theme: Start to untangle GtkIconInfo

GtkIconInfo contains too much redundant data,
and it is hard to know which fields are to be
used when.

This commit starts to move towards dropping the
icon_file field - we prefer to work with the
filename directly, since it lets us avoid mime
sniffing and strdups.
