Added support to list and remove orphaned packages.

Browse Source 
A new target has been added to xbps-bin: autoremove. It works in
the same way than 'apt-get', but there's no stdin input. By default
it will list you all orphaned packages, and -f flag must be set
to really remove them.

The following is a real example for the git package, which requires
directly perl and curl-libs, and indirectly libidn and openssl.

$ xbps-bin -r ~/testing-xbps remove git
Removing package git-1.6.1.3 ... done.
$

$ xbps-bin -r ~/testing-xbps autoremove
The following packages were installed automatically
(as dependencies) and aren't needed anymore:

	perl-5.10.0 curl-libs-7.19.0 libidn-1.10 openssl-0.9.8j

If you are really sure you don't need them, use -f to confirm.
