Config selector

[Tamminen Eero <t150315@proffa.cc.tut.fi>]

I would like MiNT to have a primitive configuration file selection instead
of that 'Boot MiNT (y/n)?'. Copying those files with a boot manager is IMHO
clumsy :-).

Changing MiNT to read one of mint.cn[f123456789] files would only need
something like I wrote at the bottom (to MiNT 1.12-h3 sources, not tested).
The hardest part would be the modifying of the texts to all the needed
languages ;-).

Main.c:
---------
char *cnf_filename(char *path);

void
load_config()
{
	int fd;

	fd = (int) f_open(cnf_filename(""), 0);
	if (fd < 0)
		fd = (int) f_open(cnf_filename("\\mint\\"), 0);
	if (fd < 0)
		fd = (int) f_open(cnf_filename("\\multitos\\"), 0);B
	if (fd < 0) return;
	do_file(fd);
	f_close(fd);
}
