Title: [New] Support `$` and `$$` as formula delimiters.

Although the standard formula delimiters for latex formulas is currently
`\(` and `\[`, the `$` syntax has an advantage from the point of view of
writing speed, very important if we want to use *gollum* as a writing
tool.

The code includes support for escaping of the `$` symbol by using the
gollum escape symbol `'`.
