Emily Eisenberg d61a04c80d Fix up small problems with #126 
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

How to generate new metrics

There are several requirements for generating the metrics used by KaTeX.

  • You need to have an installation of TeX which supports kpathsea. You can check this by running tex --version, and seeing if it has a line that looks like

    kpathsea version 6.2.0

  • You need the JSON module for perl. You can install this either from CPAN or with your package manager.

  • You need the python fontforge module. This is probably either installed with fontforge or can be installed from your package manager.

Once you have these things, run

make metrics

which should generate new metrics and place them into fontMetrics.js. You're done!
