Use the disc list style type

[camelid]

Previously, it was the circle list style type, but it was determined
that the disc list style type is in many ways a better match for Rust.

See rust-lang/www.rust-lang.org#1252 and rust-lang/www.rust-lang.org#1254.

Was this the right place to edit the styles? It's all in one line, which made me think it might not be, but I don't see any other place.

This file is imported from http://getskeleton.com/, so it is not the right place to modify the style.

[camelid]

So where should I change it if not here? Should I add a new CSS file that overrides this style?

@camelid I guess you were waiting to learn where to put these custom styles no? Do you still have any interest in seeing this land?

[camelid]

@rylev Yeah, I'm not sure where to change the style. It would be nice to see this through :)

@camelid I've rebased this and moved the override to src/style/app.scss where we're already other styles

r? @rust-lang/website

[camelid]

@Turbo87 wow, thanks so much! Glad this change has been made at last. :)
