updated existing icons & created new icons using icons from designer provided folder.

Before I look closely at the existing Icon components, it's worth mentioning that this may be a good opportunity to talk about using svgo as a tool to optimize our SVG icons: https://github.com/svg/svgo. Just browsing through some of these I'm fairly sure incorporating some optimization will be a good practice and also possible to add to testing/committing workflow.

@chelshaw @pixelbandito thoughts?

@nvmusoke I'd be happy to approve this, but I agree that you should run those icons through svgo first. I remember it being pretty easy, but let me or @mdespuits know if you need a hand.

@mdespuits @pixelbandito yeah i'm gonna run them through svgo. I tested it in a new branch and it was really simple.

All the svgs i've yet to make js files for. I initially added them because i thought I needed them, but then I thought it would be easier to keep them in the same project.

My initial preference is not to keep working .svg files in the codebase, but I can see how it's a helpful way to keep track of what's left to do.

I'm ok with it.

other devs seem fine with keeping svg files in.
