CMIS Dictionary Refactor

- follows pattern of Alfresco Dictionary
- simplified and much reduced DictionaryService interface
- model now compiled and cached (no more lots of small continuous object creations)
- walk model via simple getters
- validated (no dangling references)
- fix up property inheritance
- fix up sub-types for all types
- implements strict mode only for now (i.e. doesn't go outside of CMIS doc, folder, rel and policy)
- abstract helper for building other CMIS dictionaries (e.g. mapping all types in Alfresco)

Alfresco Dictionary:
- add event for initialized or re-initialized

Fix up usage in CMIS REST, Web Services and query. Tests pass.

REST support for custom sub-types and properties now reliable as constrained by validated CMIS model.

TODO:
- hook property value accessors into CMIS Dictionary
