The Telepathy extensions to the D-Bus annotation format use the node
name as a base for the proxy object name in bindings.  So we should give
the nodes appropriate names.

The files themselves are also renamed to be the same as the interface
they describe.

Also, add in tp:added elements where appropriate to indicate when things
were added to the spec.

Play() should behave exactly like PlayPause(), except when
PlaybackStatus is "Playing".

The canonical page is on the freedesktop.org wiki, now.

 * Add the freedesktop-hosted specification url
 * fix the mailing list address and mailman url
 * fix the git repository and gitweb addresses

The current recommendation to use a unix pid as a unique instance
identifier and the bus name given as an example are misleading as they
suggest that it begins with a digit, which violates the D-Bus
specification.

 * Rephrase the suggestion to use a unix pid
 * Change the example so it complies with the D-Bus spec
 * Add a note quoting the relevant part of the D-Bus spec

List changes and reset the list of corrections.

D-Bus paths cannot be empty, so we need a "magic" value.

Fullscreen (and CanSetFullscreen) allow reading and changing of the
fullscreen status of the media player (videos in particular).

Required on ArchLinux, for example.  This way the user does not have to
override PYTHON manually.

Clarify what the values of CanGoNext and CanGoPrevious should be when
the proper value is not known.

Also, some typo fixes.

Remove the errorneous </div> in EMITS_CHANGED_NONE template code
in interface.html which prevented Player_Node.html from rendering
correctly

Rationale:

  The mpris lacks a way for servers to notify clients of a change
  in a playlist attribute (its name or icon)

clients of name or icon changes

We now have minimal differences with the upstream tooling (just
index.html and style.css).

Also, ditch a couple of files we don't use.
