HomeKit: support for additional accessory types

Hey @beowulfe - Thanks for all your hard work!

Was just glancing through changes of 2.4 Milestone 5 build and it looks like OH is getting some of the ESH ontology / semantics that I believe have been causing some issues for HomeKit in OH2.

Does this mean that it will be easier for new item types on HomeKit add-on?

Thanks,
JMac
