Update icons

[mdo]

• Tons of new ones (187 total now)
• Move from strokes to fills only for sanity and consistency, rip stroke customizations

I just ran icons-prep, feel free to squash and merge @mdo when you are happy with it

[MartijnCuppens]

We can move the fill="currentColor" attribute to the <svg> itself, the property is inherited by default anyway.

[XhmikosR]

Yeah this was what I meant with manual optimization for some icons too :)

Similarly, when there is more than one path, it might be possible to do some manual opts there.

[MartijnCuppens]

I'll have a look at those manual optimizations.

Edit: I can't set up this project because of this symlink:

icons/docs/assets/icons

Line 1 in 8420fb8

/Users/mdo/work/icons/icons

Probably #6 and #8 need to be merged first.

I'll merge the other PRs tomorrow and rebase this. I still need access to the Netlify account to fix previews, though. Also, I'm not sure what our deployment plan will be.

We can use Netlify or we can maybe hook up actions and push to the gh-pages branch when we tag or every time.

Forgot to mention, the Hugo watch fix I reported will probably ship on Monday. I'll update the version after that and we should now be able to do things much more freely like mount the icons folder etc.

SVG changes are in #12, a basic script for classnames is in #11, #13 has the updated SVGO config, and #10 has the updated docs layout and ported content from my PR in Bootstrap.
