Fonts don’t show up properly

Nobody has claimed this yet.

Maybe I'm missing something, but at https://mathiasbynens.github.io/math-tex/dist/example.html it looks like the right fonts aren't being loaded, which causes the rendered math to look significantly worse. This happens because the katex.min.css stylesheet is inlined:

```
@font-face{font-family:KaTeX_Main;src:url(fonts/KaTeX_Main-Regular.eot);src:url(fonts/KaTeX_Main-Regular.eot?#iefix) format('embedded-opentype'),url(fonts/KaTeX_Main-Regular.woff) format('woff'),url(fonts/KaTeX_Main-Regular.ttf) format('truetype');font-weight:400;font-style:normal}
```

but the fonts aren't available at that path relative to the built math-tex.html (they live in bower_components). Not sure the best way to fix this as I'm not familiar with how web components are usually distributed.

Start by inspecting the built math-tex.html, the inlined katex.min.css, and the font files under bower_components. Reproduce the font-loading failure at the linked example page, then determine how the distributed build should reference or include those fonts. Done means the example loads the intended KaTeX fonts and rendered math no longer falls back to the incorrect fonts.
