Changes

State solvability requirements for discrete-valued variables

According to phone meeting decision on #2639.

Clarify that equations in discrete-time Real variables are only solved at events

Add comment regarding LaTeXML failure to treat \lstinline properly inside \caption

Fix lost white-space after \textregistered (#2708)

* Fix lost white-space after \textregistered
* Add braces around argument to \textsuperscript

Tone down syntax highlighting of recognized identifiers (#2690)

* Change syntax color from red to brown
* Adjust syntax highlighting colors
* Make plain 'keyword' style pop out in bright red (should never be seen)
* Add commented-out attempt at getting nice listings comments in PDF build
* Use the hyperref 'hidelinks' option to avoid distracting links
Readers will expect things a linked anyway.
* Use darker green for comments
* Remove special de-highlighting of semicolon
Regardless of whether this is nice or not for the semicolon at the end of elements, it makes no sense to apply styling that also affects the semicolon used as an array concatenation operator.

Ignore errors in Makefile targets 'clean-pdf' and 'clean-html'

Revert to off-the-shelf LaTeXML-maybeMathJax.js

Our file was identical to the original one, so it is better to just as for the original, so that we can automatically benefit from upstream improvements.
