Add mention to RFC 940 in the Rust Reference.

This PR adds a mention to hyphens in Cargo package names being replaced by underscores when used as a crate, as per [RFC 940](https://github.com/rust-lang/rfcs/blob/master/text/0940-hyphens-considered-harmful.md)

It also formats the RFCs consistently as RFC XXX instead of RFCXXX.

When naming Rust crates, hyphens are disallowed. However, Cargo packages may
make use of them. In such case, when `Cargo.toml` doesn't specify a crate name,
Cargo will transparently replace `-` with `_` (Refer to [RFC 940] for more
details).
Here is an example:
```{.ignore}
// Importing the Cargo package hello-world
extern crate hello_world; // hyphen replaced with an underscore
```
