Introduce more flexible mounting.

Prior to this commit, a route with a URI of `/` could not be mounted in
such a way that the resulting effective URI contained a trailing slash.
This commit changes the semantics of mounting so that mounting such a
route to a mount point with a trailing slash yields an effective URI
with a trailing slash. When mounted to points without a trailing slash,
the effective URI does not have a trailing slash.

This commit also introduces the `Route::rebase()` and
`Catcher::rebase()` methods for easier rebasing of existing routes and
catchers.

Finally, this commit improves logging such that mount points of `/`
are underlined in the logs.

Tests and docs were added and modified as necessary.

Resolves #2533.
