    docs: define semantics of vncpasswd in xl.cfg
    
    A recent discussion around LSN-2016-0001 [1] included defining
    the sematics of an empty string for a VNC password. It was stated
    that "libxl interprets an empty password in the caller's
    configuration to mean that passwordless access should be permitted".
    
    The same applies for vncpasswd setting in xl.cfg. This patch
    extends to xl.cfg documentation to define the semantics of setting
    vncpasswd to an empty string.
