Use LaTeX delimiters by default, add /tex command

Browse source 
Since parsing for $'s as maths delimiters is tricky, switch the default
to \(...\) for inline and \[...\] for display maths as it is used in
LaTeX. Add /tex command to explicitly parse in TeX mode, which uses
$...$ for inline and $$...$$ for display maths.
