Google hash classes

[Aleix Pol]

Hi,
I just remembered we have these classes in our codebase
(kdevplatform/utils/google) and I thought that it might be a good idea to
use a newer version [1]. According to the changelogs there's been many
improvements.

Also I saw that we're installing these classes, it's not being used in
KDevelop, so I'd suggest to stop installing those classes' headers. Also
they're not being exported as well.
