* 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
