[Feature] More Formatting Tags for Paper

[CameronWoof]

This patch adds headings, horizontal rules, blockquotes and bulleted lists to the sanitized formatting section. 

It also cleans up the appearance of paper; paper you name is no longer "paper - thingyounamedit" but just "'thingyounamedit'" instead. The baby quotes are still there so that you know it's a paper titled something.

EDIT: added blockquote

Oh, nice patch.

If this gets implemented can the wiki be updated as well?

I would do so/attempt to do so, yes.

Good stuff! Do merge.

Patch on hold after a discussion in IRC about the in-efficient over-use of replacetext() and my subsequent promise to code a bbcode/markdown parser datum as a result.

Sidenote: why do I keep promising to do these things fuck
