Better support for voice notes.

Better support for voice notes.

Hello!

I see some opportunity for make a better "voice note" use on Cliq like another messanger-app.

- Downsize the format file for fast transfer and low use of data (Not use .WAV, use MP3 ex.)
- Using the name-user-chanell-time to make a more easy search and find notes (not 1531412354131.wav, more human read like SalesChannel-Stevens-20180209-21:33PM.mp3)
