UI - Add Volume Controls + Mute Toggle (F2) (#2871)
* Add the ability to toggle mute in the status bar.

* Add the ability to toggle mute in the status bar.

* Formatting fixes

* Add hotkey (F2) to mute

* Add default hotkey to config.json

* Add ability to change volume via slider.

* Fix Headless

* Fix SDL2 Problem : Credits to d3xMachina

* Remove unnecessary work

* Address gdk comments

* Toggling with Hotkey now properly restores volume to original level.

* Toggling with Hotkey now properly restores volume to original level.

* Update UI to show Volume % instead of Muted/Unmuted

* Clean up the volume ui a bit.

* Undo unintentionally committed code.

* Implement AudRen Support

* Restore intiial volume level in function definition.

* Finalize UI

* Finalize UI

* Use clamp for bounds check

* Use Math.Clamp for volume in soundio

* Address comments by gdkchan

* Address remaining comments

* Fix missing semicolon

* Address remaining gdkchan comment

* Fix comment

* Change /* to //

* Allow volume slider to change volume immediately.
Also force label text to cast to int to prevent decimals from showing in status bar

* Remove blank line

* Undo setting of volume level when "Cancel" is pressed.

* Fix allignment for settings window code
