Multiscreen patch ported to CVS.

[Andrew V. Samoilov]

Hi!

I ported Walery's Multiscreen patch to CVS version. It can be uploaded from
http://www.linux.zp.ua/mc/mc-cvs-multiscreen-0.6.patch.gz.
It based on 
http://www.sama.ru/~despair/mc/mc-multiscreen+bookmarks-patch-0.5.tar.gz
for mc 4.5.55.

I added autoconf (--enable-dlgswitch) and automake support, fixed 
compilation
with egcs-1.1.2 and some features.  It is compiled but I had no time to 
test it hardly.

Known bug in built-in editor: if you edit file with relative filename 
(common place with F4)
and switch to file manager and change directory, this file will be saved 
relative your current
directory.  There is a dir field in WEdit structure, but it is not used 
properly.

Regards,
Andrew.

P.S. I am going to Moscow tomorrow for 2-3 weeks and will have limited 
access to Internet this time.
