feat(widget): expose pulse to the widget (to get volume and mute status)

[mokasin]

Why do you want to let the widget expose pulse? Can you explain your use case? Seems to me, that would be only needed to move logic into your configuration file, which I personally would discourage.

Thx for your contribution.

no, as i stated in the commit message, i just need to know mute state and volume from the outside of the widget

So basically pulseaudio.lua should be a separate module apart from the widget itself, in order to do this cleanly. But I guess, since the change is really marginal, it wouldn't really hurt.

thanks!
