Also update MathCaptcha so that it works with recent versions of
Math (and breaks with old ones). Also fix MathCaptcha API output,
which used to send the question in plaintext.

Zopfli is the most efficient DEFLATE compression algorithm, trading run-time
performance for file sizes that are typically 3-8% smaller than those produced
by zlib with the maximum compression setting. Its output is Deflate-compatible,
so no specialized decoder is needed.
This change was created by running zopflipng against all the PNG files in this
repository. The exact invocation was:
git ls-files --exclude-per-directory=.gitignore -- '*.png' \|
parallel zopflipng -m -y --iterations=500 --filters=01234mepb {} {} \;
Files which zopflipng was not able to compress more efficiently were left unmodified.

that is actually specific to CreateAccount.
