Healthchecks

This release contains a backwards-incompatible change to the Signal integration (hence the major version number bump). Healthchecks uses signal-cli to deliver Signal notifications. In the past versions, Healthchecks interfaced with signal-cli over DBus. Starting from this version, Healthchecks interfaces with signal-cli using JSON RPC. Please see README for details on how to set this up.
