Although defaulting to wayland-0 seems convenient, it has an undesirable
side effect: clients may unintentionally connect to the wrong compositor.
Generally, it's safer to fail instead. Here's a real example:
In Fedora 22, Gtk+ prefers Wayland over X11, though the default session is still
a normal X11 Gnome session. When you launch a Gtk+ app, it will try Wayland,
fail, then try X11, and succesfully start up. That works fine.
Now suppose you launch Weston while running the Gnome session. Suddenly, all
of the Gtk+ apps launched from Gnome will show up inside Weston instead.
That's unexpected. There's also no good way to prevent that from happening
(other than perhaps setting WAYLAND_DISPLAY to an invalid value when launching
an app).
Not using wayland-0 as the default will solve that problem: an app launched
from the X11 Gnome session will use the X11 backend regardless of whether
there's a wayland compositor running at the same time.
Everything else should work as before. The compositor already sets
the WAYLAND_DISPLAY when starting the session, so the lack of the default value
should not make a difference to the user.

Just to make it slightly shorter.
Also add a dash to the doxygen links to make them look a bit more alike.

There have been a lot of questions asked lately about versioning of
interfaces and protocol objects. This addition to the documentation should
clear up some of those questions.

The method described of alocation IDs has been wrong at least since version
1.0. This commit updates it to correspond to the way IDs are chosen in
versions >= 1.0.

This directory was called Wayland during my early tries with publican where
the source layout was different and it needed to be set to the same name as
the publican output directory. This reason doesn't exist anymore, so re-name
it to publican to make it more obvious what's hiding in here.
