v1.5 General improvements and fixes

This release includes the following new functionality:

• clear command that lets you manually clear the transcript before detection ends. This lets you more easily parse out wake words in protoflux. Includes an event to notify you when the transcript was cleared. This can be finicky since Google's STT sometimes changes words as it gains more confidence in its prediction. A future update will include custom timeouts and confidence thresholds to make this easier to work with.
• Debug mode - This shows you the confidence value for the current prediction. Includes both a UI element as well as a new event to report the confidence to flux. A future update will include requiring a custom confidence threshold to be met before appending to the transcript.

The syntax for commands and events has changed. Commands no longer require special characters on either side, and events are now wrapped in square brackets (ie: [enabled])

Additionally transcriptions should no longer send duplicate messages that contain no new text. A new transcription event will only be sent if the previous transcription was detected as complete (determined by Google automatically, for now), or if new text is present.
