Quickly mute tabs with keyboard shortcuts

Keyboard shortcuts for muting tabs.

Default setup:
- Mute/Unmute current tab - Alt + Shift + M
- Mute all except current one - Alt+Shift+N
- Mute/Unmute all tabs - Alt + Shift + Comma

Keybindings can be edited through the ""Keyboard Shortcut"" menu at the bottom right in the Chrome extension settings.
Or past this in the omnibox:
chrome://extensions/shortcuts
