Selectable audio device

There is now an option to select the audio device, overriding the default audio device currently selected.
The addition of this release, hence, should solve issue #13.

Release includes everything else introduced in v1.1 build 6/beta 3.

A big thank you especially for @hatemosphere for the recent sponsor!
Also thanks to sponsors @ckortekaas, @luisrjr and an anonymous sponsor for sponsoring this project earlier!

Thanks for all your support!
