Remove <br>s

There shouldn't be `<br>`s after the TOC according to the [HTML5 spec](http://www.whatwg.org/specs/web-apps/current-work/multipage/text-level-semantics.html#the-br-element).

> The br element represents a line break.
>
> **br elements must be used only for line breaks that are actually part of the content, as in poems or addresses.**
>
> br elements must not be used for separating thematic groups in a paragraph.
>
> If a paragraph consists of nothing but a single br element, it represents a placeholder blank line (e.g. as in a template). Such blank lines must not be used for presentation purposes.
>
> Any content inside br elements must not be considered part of the surrounding text.
>
> 

Since the line breaks are being used for appearance instead of content, I removed them. Any space that needs to be there can be added through CSS.

Cheers :)

P.S. My editor stripped a bunch of trailling whitespace...
