Add new --needed option for -S.

During a pacman operation such as a group install, pacman can ask several
questions such as "local version is up to date. Upgrade anyway?". They are
usually all answered either by yes or by no:
* yes when you want to reinstall all the targets.
* no when you only want to install the missing ones (either because you are
installing a group, or because you are copying a pacman -S line from wiki or
whatever).

So instead of asking this question for each target, it is now now configured
with a flag.  Yes will be the default -S behavior, No will be achieved with
the --needed flag.
