Summary:
Add a way to automatically build vlists correctly. Previously, we built
vlists manually in ~4 different places, which made it difficult to manage
changes, and led to a large amount of duplication in the less. This also fixes
the vlist construction in safari, where the `display: inline-table` wasn't being
applied because of CSS specificity. This leads to the only significant change in
the huxley tests, with the vertical spacing.
Test Plan:
- Make sure the tests still work
- Make sure most of the huxley screenshots didn't change, and that the new
changes are insignificant.
- Make sure vlists now work in Safari
- Make sure the change to the VerticalSpacing screenshot is caused by the
fix-baseline span now correctly applying `display: inline-table` by creating
the construct in master and adding `display: inline-table !important` to the
`.fix-ie` css rule

Summary:
Follow the TeXbook instructions on how to construct square roots. Using
makeCustomSizedDelim, this becomes nearly trivial.
Test Plan:
- Make sure normal tests work
- Make sure the new huxley test looks good, and other huxley tests haven't changed.

Summary:
Added stacked delimiter support for more delimiters. Split out delimiter
functions into its own file, and split out some tree building functions into a
common file. Supports the empty `.` delimiter with \left and \right, and doesn't
try to produce huge /, \backslash, <, or > delimiters. Depends on D7844
Test input:
\left( \left) \left[ \left\lbrack \left] \left\rbrack \left\{ \left\lbrace
\left\} \left\rbrace \left\lfloor \left\rfloor \left\lceil \left\rceil
\left\langle \left\rangle \left/ \left\backslash \left| \left\vert \left\|
\left\Vert \left\uparrow \left\Uparrow \left\downarrow \left\Downarrow
\left\updownarrow \left\Updownarrow {x^{x^{x^{x^{x^{x^{x^{x^{x^{x^x}}}}}}}}}}
\right.\right.\right.\right.\right.\right.\right.\right.\right.\right.
\right.\right.\right.\right.\right.\right.\right.\right.\right.\right.

Test Plan:
- Run the test input, see that it works
- Run the tests, see that they work
- Look at huxley screenshots (not here yet :( ) and make sure they look good
