The editor framework

The purpose of this module is to provide a framework making it easy for others
to build an editor.

The framework is a layered model consisting of:
- Layer 0: Javascripts that to the actual editing on the page
- Layer 1: Toolkit implementation (specific to different toolkits)
           included in the layer is the actual graphic setup
           This code will only be suplied as example code
- Layer 2: API to Layer 1
- Layer 3: Editor handling (start JS receive input back)
- Layer 4: Connection to DocFormats.

The current idea is to develop the framework using Qt as Layer 1 (example code)
and then test the API with a server implmentation.
