[volume] BREAKING CHANGE - new widget instead of old ones

Having three widgets for volume led to a problem of code duplication -
same logic was duplicated three times. However when an issue was
discovered and fixed, it was fixed in only one of three widgets.
So I decided to create a volume widget from scratch, adding new
features, such as selecting input/output, better responsiveness,
easily customizable widget ui (bar, text, icon, icon and text, arc).
Should close #199, #198, #185, #182, #47, #122, #183.
