* `\relax` is now implemented as a function. It'll stop
expansions and parsing, so the behavior around `\relax` may change.
For example, `\kern2\relax em` will no longer work.

### Fixed
- Note: The v0.8.0 release did not include the SVG images which are necessary for rendering wide and stretchy accents as well as `\overbrace` and `\underbrace`. This release corrects that.

- Note that if you're including copies of KaTeX in your web application, you should now include the dist/images directory in addition to the usual the dist/fonts directory.
