* configure.in: Deleted du checks

* INSTALL: Deleted --with-dusum documentation.

* doc/mc.sgml, mc.1.in: Completed documentation about the Options/
Configuration dialog. Added Advanced chown subsection. Deleted
variables from the Special settings section which are now covered
by the configuration dialog.

* gnome/layout: Adapted for the new option Compute Totals in the
Configuration dialog.

* screen.c (recalculate_panel_summary): new function which recalculates
the summary information for the mini-status.

* screen.c (panel_reload): use recalculate_panel_summary

* screen.c (do_file_mark): Honour that dirsizes computed is now a
per entry flag.

* option.c: Added Compute Totals to the configuration dialog.

* file.c (compute_dir_size): made non static

(panel_operate_flags): Don't compute directory sizes if verbose
operation are off.

* cmd.c (dirsizes_cmd): Rewritten to use compute_dir_size as suggested
by Miguel, i.e. get rid of du. Now the dirsizes_cmd honours a
selection and computes sizes only for marked directories. Possible
improvement: add a dialog (or C-C?) to abort computation.

* dir.h (file_entry), panel.h (WPanel): Made the dirsizes computed
flag a per file flag.

* dir.c, find.c, panelize.c, screen.c: Adapted to new file_entry and
WPanel structure.

* features.inc: Deleted DUSUM information

* mc.hlp: remade because of changes in doc/mc.1.in
