Feature Request/Patch: Allow configuring the volume controls' and signal strength bars' colors.

[m7a]

I find it a little confusing that volume control and signal displays are colored in the same colors. I guess this is only due to personal preference, though. Thus I wonder whether having configurable foreground colors for the individual parts of the bars could be beneficial?

A patch for bf4acb3 acting as a proof-of-concept is attached.
In case it looks good enough, it is of course also possible to apply it; in case it is easier to handle, I can of course alternatively try to open a pull request instead :)

Interesting idea, although I'm not a big fan of adding more hard to read numeric colors into the configuration.

Also while we're at it, we might as well toss the idea of low,medium and high and just let the user create those distinctions in the config.

Wrt. hard to read: I think I can come up with an improved version that would use more readable names, it will just take some time :)

Regarding the configuration of the areas: I am not sure how useful this is for a "global" configuration because most likely, the "good signal" area will depend on the actual device in use? But then again, I am not really an audio expert...

Update: Improved patch to use color names rather than numbers. Now against current dev (ec3a383)

Another thing that I would love to configure is the unicode characters used for drawing. Reasons: I might want to experiment with using the "large block" characters (e.g. █░▒▓) for signal strengths/loudness and regular ASCII for mute/unmute symbols (as they are not displayed correctly here and I do not want to have Emoji in my terminals anyways :) ).
