I've added a first simple parser for the crankstart format, it supports classpath, bundles and configuration for now.
Now, the major difference between crankstart and all other models is that crankstart describes actions - most of them (like the above, start level changes, osgi properties) can be translated into the model. Others like, logging, stopping the instance etc. can't. I'm not sure if we need this flexibility and/or how to handle it.
