In case sensitive sort, the order of files and directories is following:
hidden dirs
dirs
hidden files
files
In case insensitive mode, directories are mixed and files are mixed too:
dirs (hidden and not are mixed)
files (hidden and not are mixed).
This commit defines the sort order independently of case sensitivity:
hidden dirs
dirs
hidden files
files
Files in UTF-8 locale require special handling: leading dot must not be
processed in g_utf8_casefold() funcion.
