Replace the switch plugin with the selector plugin. Add output-
selector as the opposite of input-selectoo (was switch). Add a test
for output-selector. Add docs for the elements. The vcproj needs
update. Fixes #500142.

-   * A switch over multiple switch elements should be performed as follows:
-   * First, emit the <link linkend="GstStreamSelector-block">block</link>
-   * signal, collecting the returned values. The maximum running time returned
-   * by block should then be used as the time at which to close the previous
-   * segment.
-   *
-   * Then, query the running times of the new audio and video pads that you will
-   * switch to. Naturally, these pads are on separate switch elements. Take the
-   * minimum running time for those streams and use it for the time at which to
-   * open the new segment.
-   *
-   * If @pad is the same as the current active pad, the element will cancel any
-   * previous block without adjusting segments.
