Add information on how an installed package was validated

When installing a package, store information on which validation
method was used and output this on "pacman -Qi" operations.

e.g.
Validated By   : SHA256 Sum

Possible values are Unknown, None, MD5 Sum, SHA256 Sum, Signature.

Dan: just a few very minor tweaks.
