Cleanup non-essential options from vnc_lite

This is supposed to be a simple example, it shouldn't have this many
options. This commit removes the following options:
 * logging - the default level 'warn' is good enough
 * title - a weird thing to set from the query string anyway
 * token - not used by most setups
 * encrypt - looking at the URL is good enough
 * repeaterID - not used by most setups
 * shared - uncommon setting
 * resize - not supported by most servers

Note that the removal of 'encrypt' allows us to remove logic for
establishing a default port. The default port for wss is 443 and for ws
it's 80 anyway.
