• Many small optimizations and improvements in the CSE's internal handling, especially for internal resource object creation.

Fixes

• Fixed partial attribute retrieval for <flexContainer> specializations.
• Improved stability of the CoAP protocol binding in case of listening errors.
• Fixed regression bug when using newer versions of the isodate package.
