Summary:
Update the MathJaxFonts `Dockerfile` to enable the use of
`ttfautohint` which hints our fonts better. Also, fix the location that
batik is downloaded from, update some formatting in the `Dockerfile`,
and update the fonts and metrics.
Test Plan:
- Compare a rendered `= - A z 4 \Longrightarrow \Sigma \Biggl(` in
Chrome on Windows at font sizes 10px to 20px before and after this
change.
- See that characters look about the same, or better.
- See that the screenshot tests didn't change in firefox (maybe firefox
runs the same autohinting algorithm that we do?), and don't visually
change in chrome

Summary:
To complement pull request #142, add the ability to automatically
generate the woff2 files from within the docker. Add a script for copying out
the generated font files to make things easier. Remove the KaTeX_Greek font
files as well as the KaTeX_Win ones, since we don't use them and they're oddly
non-woff and non-eot specific?
Test Plan:
- Build a new docker from the new Dockerfile
- Make sure the woff2_compress program compiles
- Follow the instructions in the README to build the fonts
- Make sure the fonts correctly build
- Make sure the copy_fonts.sh script copies the fonts out

Summary:
This incorporates the changes to add a KA copyright, and to generate the woffs
from the ttfs, not the otfs.
Test Plan:
- Run huxley tests, see very little has changed (it looks like all the images
shifted back down ~1/2 pixel, the opposite of what happened in ad97dab19c
when we started making our own woffs, which means we probably are now
generating woffs the same way fontsquirrel does)

The OS/2 values in the generated fonts were incorrect, so this corrects them. To
do this, I added some files to the khan/MathJax-dev repo, and updated the
dockerfile to use the new repo.
Test Plan:
- View the test page with chrome and firefox on linux, chrome and safari on mac,
and IE8 and IE9 on windows, and see that none of the characters are clipped.

Summary:
Also, rename all of our uses of fonts to use the uppercased versions. We want to
use the uppercase versions because it makes updating and modifying the fonts
much easier (since the font names inside the actual font files are uppercased).
Test Plan:
- Make sure the huxley screenshots look good (You can compare a diff of them
on github at
f90d093361
By my eye, it seems like some things have moved up ~1/2 pixel, and some of
the fonts have maybe slightly changed shape, like the large `b` in
SizingBaseline)
