Simplifies whitespace control and adds an option

[JaneOri]

Simplifies whitespace control and adds an option for clearing whitespace without leaving any output behind.

Adds:

Special Case

You may want to remove all whitespace between elements without output or comment.

<ul>
	{{--}}
	<li>Inline Nav Item 1</li>
	{{--}}
	<li>Inline Nav Item 2</li>
	{{--}}
</ul>

would render as:

<ul><li>Inline Nav Item 1</li><li>Inline Nav Item 2</li></ul>
