Kaithem

- Fix creating new tags via the GUI
- Fix incorrect initial state shown in freeboard
- Fix fade in/out of sounds
- Fix Chandler race condition where stop commands could come before start commands

- JackMIDIListener has been removed. Instead, all connected ALSA midi devices automatically generate tag points for last pressed note and all CC values.
- All connected midi devices now also report to the message bus
- JackFluidSynth plugin now only accepts MIDI on the internal message bus.
- python-rtmidi is required to use these features. This is all on account of some unreliable performance and excess complexity with jack midi.
- Chandler can now respond directly to MIDI, no code needed
- Chandler bugfix with smart bulb hue and saturation channels not blending the way you might expect.
- Using a caching strategy we avoid calling ALSA sound card listing functions when not needed to stop occasional bad noises(Much lower JACK latency is possible)
- Chandler Pavillion encrypted protocol sync removed(MQTT alternative coming soon)
- Chandler scene notes now just uses a plain HTTP textarea

- *Major breaking changes*

- The ALSA sound card aliases system has been removed. We no longer support multiple devices except with JACK
- Audio file playback is now done with libmpv. All other backends are deprecated. You should have python-mpv on your system!
- This greatly increases audio performance and stability.
- We no longer support a2jmidid or aliases for MIDIs. Use ALSA midi directly, almost no use cases will need advanced routing.

- Now we support those cheap SainSmart relay boards with a tagpoint based interface. Use the Relayft245r device type.
- Freeboard default values don't clobber existing stuff if it is there, for the slider and switch widgets.
- Broadcast Center sends snackbar text alerts to most/all devices accessing the server
- kaithemobj.widgets.sendGlobalAlert(message, duration) to programmatically send HTML in a snackbar to all devices.
- New tag.control: expose API gives write only control, for when you want to both claim the tag and separately see it's current real value
- New /pages/chandler/sendevent?event=NAME&value=VALUE API
- User pages now show telemetry on what WS connections are open from what IP addresses on what pages. Use
- BREAKING CHANGE: the default topics used by the MQTT Tag sync no longer use a slash.
- Correctly handle MQTT passsive connections that are created after the real connection

- Avoid slow cue transition performace when there is a cue loop
- New compatibility/dummy mode for managing jack(Gives better performance on some systems, can work on new raspbian)
- Freeboard now supports both click and release actions for buttons
- Fix nuisiance error logging in chandler console inspect window

- Corerctly autocreate the log dir
- Storing devices in modules

- Fix tag point subscriber not firing immediately in some edge cases
- Bigger text boxes on tag point pages, for longer expressions
