Better whitespace handling and control (#145)
* Fine tune whitespace

The EEx outut now emits more human-readable and predictable formatting.
This includes proper indenting, at least for each "root" template.

* Internal whitespace control

You can now use a bang version of any nonvoid tag to emit the markup
witout the internal whitespace. This means that there will not be a
newline emitted after the opening tag and before the closing tag.
