Refactor CMIS Dictionary part 2

- further simplification of CMISDictionaryService and fixup fallout
- added logging
- consolidate & fix property definition handling (only one definition per property)
- include support for aspect properties
- fix property.isInherited
- open up the door for types outside of CMIS doc, folder, rel & policy

Dictionary Service
- add isOverride() to PropertyDefinition

Invite Workflows
- ensure they create their own namespace for new types/props
- NOTE: the previous way uses a hole in the DictinaryService which has been there
        unnoticed for over 4 years, till now. At some point, the hole will be filled in.
        
Tests pass for CMIS REST / Web Services and Query.
Tests pass for Invitation Service.
