Subject: [PATCH] Add option to disable just `$...$` math, not `\(...\)` math

Unlike pandoc itself, vim-pandoc-syntax eagerly treats everything after
a `$` as inline math. The workaround for pandoc markdown documents that
make heavy use of `$`-based prices is to use `\$`, which both pandoc and
vim-pandoc-syntax recognize as a literal dollar sign.

Personally, I would rather have `$` always mean a dollar sign, and use
`\(...\)` for inline math, because I never use `\(...\)` for anything
else.

With that in mind, I've added a way to disable all special behavior for
`$...$` inline math.
