move client classes into akonadi2common and add the base class for resource plugins

we can divide up libakonadi2common later once we have a full collection of classes
this makes writing code a bit simpler now as we don't have to figuer out which
libraries to link against or how class dependencies should look. when we have
more infrastructure in place this will mostly become self-evident
