Merge the new message viewer from akonadi-ports. It's based on the KMail one and got all its features (including all the crypto stuff), but is ported to Akonadi/KMime. It is at least somewhat useable for non-Akonadi KMime-based applications (eg. KNode) as well, as an intermediate step during porting.

There is also a demo app for the message viewer and the message list,
this still has to be moved to a better place.

The merge preserves all history, so no need to put the usual svnmerge
log
here, it's way too huge anyway.
