Links in "tight" lists are not colored

[scott-ainsworth]

Markdown list items separated by blank lines are wrapped in p tags within li tags ("loose" list). formatting. List items not separated by blank lines use only li tags ("tight" list). Links in loose lists are displayed in blue and are easily distinguishable as links. Links in tight lists are normal text colored and do not appear as links (although clicking them still works). Examples of both list types follow:

Loose List (links are formatted as expected)
/// * [The Rust Programming Language](http://doc.rust-lang.org/book/)
///
/// * [The Rust Reference](http://doc.rust-lang.org/reference.html)

Tight List (links are not formatted)
/// * [The Rust Programming Language](http://doc.rust-lang.org/book/)
/// * [The Rust Reference](http://doc.rust-lang.org/reference.html)

Adding the missing formatting to loose lists is difference appears to be straight-forward CSS change. In src/librustdoc/html/static/main.css, two rules control link appearance in loose lists (lines 377 & 378 in the dfc5c0f commit):

p a { color: #4e8bca; }
p a:hover { text-decoration: underline; }

Adding a second selector to each rule colors the links:

p a, li a { color: #4e8bca; }
p a:hover, li a:hover { text-decoration: underline; }

There are only two other li rules and these do not affect color. So, the change above may be all that is needed to fix this issue.

Just patched locally and can confirm it works.

Thanks!
