070883532a Support \textup and \textmd (#1921) 
* Support \textup and \textmd

This PR adds support for `\textup` and `\textmd`, which are the inverses of
`\textit` and `\textbf`.  Unlike bare `\text`, they result in `textup` and
`textmd` classes being applied, but those have no CSS rules, so they act the
same as bare `\text`.

Fixes #1909.

647c661db0 Remove double encoding in MathML via Unicode MathML spaces (#1813) 
* Remove double encoding in MathML via Unicode MathML spaces

We used to have a complex mechanic for escaping strings, marking them as
`needsEscape = false`, and then not escaping those strings (for
combining strings in `\operatorname`).  But this doesn't really work
with `render`ing directly to a node, as `document.createTextNode` can't
be stopped from escaping.

I've thus removed this mechanic, which required the following changes:

* Switch MathML "smart space" encoding to use Unicode instead of
  `&LongNames;` (which weren't working with `render` for the same reason).
* Hack our HTML/MathML serializer to not use `String.trim`, which wrecks
  havoc with emitted Unicode spaces.

Now `toText()` doesn't escape, so strings concatenate in unescaped form,
and `toHTML()` only does the necessary escaping.  Thus fix #1782.

* Fix \\ and \newline after operator

Fix #1790.  `\\` and `\newline` render as a span with classes
`mspace` and `newline`.  We need to check for `newline` when bringing
spaces into the same `base` group.
