[aur-general] Support for remote sums in PKGBUILDs

[Ido Rosen]

- Do PKGBUILDs support signing the PKGBUILD and verifying that signature?
 (This seems like a good feature for yaourt or possible makepkg if it isn't
one already.)
  It seems like if you want safety from MITM attacks, PGP sigs are the way
to go, either sign the PKGBUILD and put the checksum in there, or include
the signature of the source file in the tarball/pkg.  (This is already
provided for binary pkgs, but not source ones, correct?  Seems easy enough
to add a PKGBUILD signature and teach makepkg to use it.)
