docs.rs link to nightly docs is broken

[icefoxen]

On this function: https://docs.rs/ggez/0.4.0/ggez/timer/fn.get_delta.html

The link to the Duration type aims at https://doc.rust-lang.org/nightly/std/time/duration/struct.Duration.html but the proper link is at https://doc.rust-lang.org/nightly/std/time/struct.Duration.html.

It looks like the organization for docs.rust-lang.org has changed out from underneath us slightly in a recent revision... On stable the first URL format works fine. Not sure whether this is a bug in rustdoc or not.

It seems nightly docs.rs has been broken for a while, see #171 .
