tidy indent fix

There has long been an issue where all kinds of elements are broken if they are indented or listed. This is because HTMLTidy does not allow block elements inside <dd> or <li>. There is no real reason why this is the case.

HTMLTidy can easily convert this properly by setting "indent: auto" in the configuration. I figured that perhaps it might be because the Wiki sanitizer produced invalid code for these situations at times, but if it did, it no longer seems to be the case.
