Performance improvements

Good day to you all,

This release delivers some much needed performance improvements with the churn as of late. More setup is done before the critical stage of adding the characteristics to the service and polling is no longer critically parsed during the "Set" events for related characteristics.
The related characteristics are now defined per device as some some characteristics are optional in different devices or have no "Target" characteristic like Temperature Sensors compared to Thermostats.

Take care,
John Talbot
