v0.5.0-pre

This prerelease allows the IP address of a Hubitat hub to be changed (#31). (In previous versions, updating the IP required the integration to be removed and re-added.) It's a pre-release because it migrates the unique IDs of all entities to a new format that uses the Hubitat MAC address rather than its IP address. If that goes wrong it's a bit of a pain to deal with. 😄

Note that once you install this version, you can't easily downgrade -- you'll need to restore a snapshot or your config directory.
