Add font data for the rest of the MathJax fonts, and support for loading them. Currently, there is support for one extra file (not the multiple extra ones from HTML-CSS).

Add support for \phantom
...
Summary:
Using \phantom with non-phantom math in Perseus doesn't render to be the
same size because \phantom uses MathJax and the non-phantom math uses KaTeX.
Implementing \phantom in KaTeX should solve this alignment issue.
Test Plan:
[x] write (and run) unit tests
[x] create (and run) screenshotter tests

Make text operators <mi>s
...
Summary: According to the MathML spec [about
identifiers](http://www.w3.org/TR/MathML3/chapter3.html#id.3.2.3.3 ),
text function names should be <mi>s. This fixes that.
Fixes #202

Make our own screenshotting script instead of using huxley
...
Summary:
Create our own screenshotting script which takes screenshots. This
improves over huxley for a couple reasons:
- It makes the screenshots the correct size (for some reason, huxley struggles
with this).
- Its configuration matches more with what we want (we don't need multiple
screenshots or interaction, we just want a single static shot)
- It runs faster
I also changed the docs to reflect this change.
Test Plan:
- Make sure all of the tests that were in the Huxleyfile are now in ss_data.json
- Run the screenshotter docker
- Make sure all of the images look reasonable and don't change (except
sometimes the Lap test, which has some strange pixel-positioning
differences...)

Simplify mfrac layout. (Don't try to force the division line to be on the baseline so that it is always raised to the correct place by a vertical align of .25em; instead, just shift the whole stack appropriately. This may cause misalignment if we can't measure the parts exactly, however, but should speed things up a bit.)

Add combineBBoxes() method, and use it in mpadded and mrow. Also use bbox.t and bbox.b to indicate the actual extent of ink (which can be altered by mpadded).
