Direct example. Move all DOM code default_controls.js.

Move DOM manipulation into include/default_controls.js and update
vnc.html to use it.

Add an example vnc_auto.html which automatically connects using
parameters from the query string and doesn't use default_controls.js.

Reorder functions in vnc.js to put external interface functions at the
top of the RFB namespace.
