Use lgi to get icons directly from GTK 

Rather than setting a path to the icons, use lgi to get the current GTK theme
and then look up the icons. Then set the image as a cairo surface by using the
GTK api directly.

With this change, one can modify their GTK icon theme (e.g. with lxappearance),
restart AwesomeWM and have the widget's icon automatically updated.

# Configuration
The widget displays volume icons that are searched in the folder defined by

icons whose extension is `".svg"`.
The widget will display the audio icons defined in your GTK+ theme and it will
resize them to fit in the available space. This means that you can switch your
icon theme, for example using `lxappearance`, and update the widget by
restarting AwesomWM.
Specifically, you will need icons named:
