Implements #277 + minor stuff and fixes

[drrmmng]

This pull request contains the following:

• Implementation for Support for PulseAudio sources in the sound block #277 through a "direction" field in the sound block. This field can be either "input" or "output" and defines whether the block is used as a sink/output/sound or source/input/microphone.

• Added support for Font Awesome 5 Icons. The icons.name field now accepts "awesome 5" as a value.

• Added microphone icons.

• Fixed a few icon bugs in the sound block.

• Fixed the icons in the xrandr block.

Things that require testing:

• Do the Material icons work correctly? I couldn't get the to work correctly even without this PR.

• Does the sound block as input work correctly with alsa? I wasn't able to test this.

Thanks, this looks like impressive work. I will try to test out the ALSA stuff sometime this week.

Is the FontAwesome 5 stuff integral to these changes or can it become its own PR? Do you think it will resolve issues like #130?

Thanks!
Yea, the FontAwesome 5 stuff should probably be a separate PR. Unfortunately I don't know how to separate them... 😀

Regarding #130: I don't think this is related, I just fixed some icons that use different Unicode IDs in FontAwesome 5.

Did you test it already? :)

Unfortunately, I am not going to be able to merge this in its current form. Couple things to note:

First, you started this branch from a commit nearly six months old. As a result, there are a bunch of legitimate merge conflicts, and the branch cannot be easily rebased against master, either. Second, the commits each make a whole bunch of unrelated changes at the same time, often overwriting previous work. This makes it very, very hard for me to assess the changes. Finally, there are a bunch of unnecessary formatting modifications that make resolving the merge conflicts very difficult.

I spent a little while trying to parcel your changes out from the individual commits, but it was too time intensive, and eventually I gave up. I'm very sorry to turn away legitimate contributions, but I don't have the bandwidth to restructure your work from this branch. My suggestion would be

1. Break unrelated changes into individual pull requests. The FontAwesome 5, xrandr, and sound icon fixes would all be welcome, but not all at once.

2. Don't bundle unrelated edits (e.g. reformatting existing code in other parts of the file) with bug fixes or improvements.

3. Try to write (or, more likely, rebase until you get) a "clean" git commit history so that I can compartmentalize your changes and understand them better.
