Title: Use presence of "data-linenum" attr as toggle to show line numbers

This PR resolves the issue raised in #6 over [here](https://github.com/jzaefferer/grunt-jquery-content/pull/6/files#L0R128), so that the data-linenum attr has to be present to activate the display of the line numbers gutter, and its value will be used only if supplied.
