** SpiceMainConn
** This is the master Javascript class for establishing and
** managing a connection to a Spice Server.
**
** Invocation: You must pass an object with properties as follows:
** uri (required) Uri of a WebSocket listener that is
** connected to a spice server.
** password (required) Password to send to the spice server
** message_id (optional) Identifier of an element in the DOM
** where SpiceConn will write messages.
** It will use classes spice-messages-x,
** where x is one of info, warning, or error.
** screen_id (optional) Identifier of an element in the DOM
** where SpiceConn will create any new
** client screens. This is the main UI.
** dump_id (optional) If given, an element to use for
** dumping every single image + canvas drawn.
** Sometimes useful for debugging.
** onerror (optional) If given, a function to receive async
** errors. Note that you should also catch
** errors for ones that occur inline
**
** Throws error if there are troubles. Requires a modern (by 2012 standards)
** browser, including WebSocket and WebSocket.binaryType == arraybuffer
**
