Summary:
Add the ability to pass in options to the render calls which contain information about the parse. This information is passed around to the parser and builder, which parse and render differently depending on the options. Currently, this includes an option to render the math in display mode (i.e. centered, block level, and in displaystyle).
Also added some changes to make it easier to add new data to functions (now that new data doesn't need to be copied into the ParseFuncOrArg data structure, it is looked up when it is needed) and has more sane support for the `'original'` argType (as suggested by pull request #93).
Test Plan:
- Make sure tests and lint pass
- Make sure huxley screenshots didn't change, and new screenshot looks correct

Summary:
- Some of the symbols were of the wrong type (I wrote some scripts to
search the TeX source for the correct types for the symbols; I should
put these somewhere for future reference)
- Some of the symbols had the incorrect unicode replacement value. I
copied what MathJax used for the ones that were wrong. In one case,
something had the wrong font, so I used the one MathJax used.
- Some symbols were duplicates of existing symbols, those were removed.
- Some symbols are text symbols that aren't usable in math mode (maybe
they should be text symbols?) (`\aa`, `\AA`, etc.)
- Some symbols didn't seem to work/I couldn't figure out how to make
them work. For example, `\imath` and `\jmath` require an italic font
in KaTeX_Main, but we don't have the ability to do that yet. `\dots`
was removed because it's not an ordinary symbol. `\*vert` were
removed because I don't understand what they're for, nor what they
should look like.
- Some symbols weren't actually in the KaTeX fonts; to make sure they
don't fall back to something weird, I removed them. (`\S`, `\pounds`,
etc.)
Test plan:
- `make test`
- See that all of the symbols in: `\equiv \prec \succ \sim \perp
