Add Source Code Pro font family for better rendering of powerline symbols

[strazto]

Resolves #9 , please wait until I can remove the vagrantfile & feel free to squash this

Hey, @matthewstrasiotto ! Am I missing something? On my end it looks like in the screenshot bellow, and the spacing is way too big.

If it's supposed to look like this, and it's not just some problem on my end with the build (🤔), then I would not like to have this as the default font - instead it should be a config on the client/frontend side, where the user can choose the SourceCodePro font if they want.

[strazto]

That looks munted. I'll run my own build, but that's not a normal effect of the font.

You could try commenting my changes in the js & cleaning/rebuilding the frontend/project, to see what happens

Also, source code pro isn't the only way to get powerline symbols, i think I've seen people combine powerline fonts w/ whatever monospace they're keen on

[strazto]

I think the default font is courier new.

@elisescu the reason the appearance was way off was that the css styles I'd given were first resolving locally installed fonts (systemwide), then falling back to a URL, but I think I messed up the URL, maybe?

So on my machine they used my local fonts, and worked well, but you don't have them installed & the fallback didn't work. I'm fixing this now

Something isnt quite commuting about serving up the fonts. They appear to be getting bundled to public and assete_bundle.go too, but I cant see them with the inspector.

I could probably revert to how i had it, where it attempts to use local fonts, but extend it to fracefully degrade to a websafe font , but i want it to feel more portable than that and less system dependent

[strazto]

@elisescu this is ready to merge (preferably squashed, unfortunately it involved a lot of trial & error), though assets_bundle.go hasn't been regenned, I'd prefer that be done after merging.

One npm dependency was added, file-loader , which neccesiated a merge on the lockfiles.

I'm going to submit a new PR on a clean branch
