this commit makes it possible to run xorg/jwm desktop/rox filer.

renames puppy scripts which have the name of regular executables (e.g. df,
mount, etc); they will be converted back to the original name at pinstall.sh
time (with the original binary renamed to -FULL).

Merge all pinstall.sh code deb-build branch here (mime update, input_id, etc).

deb-build.sh: install base-arch first before base.
deb-build: ability to build without system dpkg.

use env var WITHOUT_DPKG=1 to enable it.
%bootstrap install now works using ar and tar.
%dpkg is redirected to %dpkgchroot
%remove is done manually.

Note that %dpkgchroot requires minimal libraries and obviously dpkg itself
to be installed in the chroot; if this is not the case then both it and
%dpkg (when using WITHOUT_DPKG) will fail. In this case, use %bootstrap
instead.
deb-build: fixes for manual removal.
Merge pull request #473 from puppylinux-woof-CE/woof-next-james
