MathML: fixes and additions.

Math accent commands more similar to their LaTeX behaviour.

Additions for HTML export.

Use boolean values for boolean node arguments.

Downcase node arguments before storing.

Use class argument "boldsymbol" for \boldsymbol content.

Alignment of multi line equations similar to AMS-LaTeX "align" environment.

Add space after bracket in "cases" environment, left-align columns.

Fix spacing before "unary" minus.
