Using strings to identify equal events is terribly inefficient. By
keeping a global list of event types we can assign each event a
numerical type index and use that to compare them.

We can also avoid excessive string copying and data duplication by
referring to the global type list where event type information is
needed.

The model manager should only set its state to 'Done' if all models are
actually done. When that is the case it can safely emit dataAvailable,
too, freeing us of the need to apply a heuristic to the progress
percentage. In order to have a unified interface to the completion of
model processing an abstract base class for QML and V8 models is
introduced.

The complete qml emulation layer (instances) is moved
into another external process (qmlpuppet).

Summary of architectural changes:

- Asynchronous messaging
    Handling commands and data transfer asynchronously reduces the
    amount of context switches between processes.

- Proxy classes for client process
    This classes abstract the inter process communication

- QVariant based command parsing and serialization
    Using LocalSocket in bidirectional manner for communications
    of commands and data transfer.

- Integer based identifier instead of ModelNode in client process
    The qml emulation layer (instances) has no more depencies to our
    internal data model.

- Timer based rendering
    Rendering in instances is controlled by a timer. Only dirty items
    are updated.
