vnc: add alpha cursor support

Browse source 
There is a new vnc extension for cursors with an alpha channel.  Use
it if supported by the vnc client, prefer it over the "rich cursor"
extension which supports only a bitmask for transparency.

This is a visible improvement especially on modern desktops which
actually use the alpha channel when defining cursors.
