Help+Base: Add help://man URLs for links between man pages

The URLs of the form `help://man/<section>/<page>` link to another help
page inside the help application. All previous relative page links are
replaced by this new form. This doesn't change any behavior but it looks
much nicer :^)

Note that man doesn't handle these new links, but the previous relative
links didn't work either.

When a process executes a normal binary, all three IDs are set to the parent process's user ID.
