Plumbing for CMIS Allowable Actions

Browse Source 
- add CMIS enum for Allowable Actions
- introduce Action Evaluator, with Permission based and fixed boolean implementations
- registry of available action evaluators based on CMIS type
- CMIS Type Definition has getter for applicable action evaluators
- couple of CMIS actions registered

TODO:
- register all actions as defined in spec
- serialize in AtomPub binding
