Feature/ul li updates

Update to the way ul/li is displayed.

1. Updated ul's to include an additional newline for starting ul's only.
This makes them appear more correctly with markdown parsers (including the
"official" one @ https://github.com/michelf/php-markdown.

2. Moved the spaces on list items before the item rather than after. This
makes it easier to read and is more in line with what most markdown looks
like.
