The net effect of this commit is three-fold:
* A request to `/` now matches `/<a>`. `/foo/` matches `/<a>/<b>`.
* A segment matched to a dynamic parameter may be empty.
* A request to `/foo/` no longer matches `/foo` or `/<a>`. Instead,
such a request would match `/foo/<a>` or `/foo/`.
The `&str` and `String` parameter guards were updated to reflect this
change: they now error, with a newly introduced error type `Empty` in
the `rocket::error` module, when the parameter is empty. As this was the
only built-in parameter guard that would be effected by this change (all
other guards already required nonempty parameters to succeed), the
majority of applications will see no effect as a result.
For applications wanting the previous functionality, a new
`AdHoc::uri_normalizer()` fairing was introduced.
