Created the possibility to send audio as an attachment via the dashboard.
The channels that can send audio are the same channels that can send any type of attachment.
Used RecordRTC (https://github.com/muaz-khan/RecordRTC) to capture the audio and Wavesurfer (https://github.com/katspaugh/wavesurfer.js) to display the audio waves.
RecordRTC can be used to record videos if necessary.
Fixes#1973
