    The optional opt paramater may be an object with any (or all) of
    the properties documented for WhAjaj.Connector.options.ajax.
    Properties set here (or later via modification of the "options"
    property of this object) will be used in calls to
    WhAjaj.Connector.sendRequest(), and these override (normally) any
    options set in WhAjaj.Connector.options.ajax. Note that 
    WhAjaj.Connector.sendRequest() _also_ takes an options object, 
    and ones passed there will override, for purposes of that one 
    request, any options passed in here or defined in 
    options set in WhAjaj.Connector.options.ajax. Note that
    WhAjaj.Connector.sendRequest() _also_ takes an options object,
    and ones passed there will override, for purposes of that one
    request, any options passed in here or defined in
    WhAjaj.Connector.options.ajax. See WhAjaj.Connector.options.ajax
    and WhAjaj.Connector.prototype.sendRequest() for more details
    about the precedence of options.
    

    Sample usage:
    

    @code
    // Set up common connection-level options:
    var cgi = new WhAjaj.Connector({
        url: '/cgi-bin/my.cgi',
        timeout:10000,
        onResponse(resp,req) { alert(JSON.stringify(resp,0.4)); },
        onError(req,opt) {

        onResponse(resp,req){ alert(WhAjaj.stringify(resp)); }
    });
    @endcode

    For common request types, clients can add functions to this
    object which act as wrappers for backend-specific functionality. As
    a simple example:
    

    @code
    cgi.login = function(name,pw,ajajOpt) {
        this.sendRequest(
            {command:"json/login",
              name:name,
              password:pw
            }, ajajOpt );
    };
    @endcode
    

    TODOs:
    

    - Caching of page-load requests, with a configurable lifetime.
    

    - Use-cases like the above login() function are a tiny bit
    problematic to implement when each request has a different URL
    path (i know this from the whiki and fossil implementations).
    This is partly a side-effect of design descisions made back in
    the very first days of this code's life. i need to go through
    and see where i can bend those conventions a bit (where it won't
    break my other apps unduly).

    doesn't even use Prototype). The Prototype version at the time

** COMMAND: cgi*
**
** Usage: %fossil ?cgi? SCRIPT
** Usage: %fossil ?cgi? FILE
**
** This command causes Fossil to generate reply to a CGI request.
**
** The SCRIPT argument is the name of a file that is the CGI script
** The FILE argument is the name of a control file that provides Fossil
** that is being run.  The command name, "cgi", may be omitted if
** the GATEWAY_INTERFACE environment variable is set to "CGI" (which
** should always be the case for CGI scripts run by a webserver.)  The
** SCRIPT file should look something like this:
** with important information such as where to find its repository.  In
** a typical CGI deployment, FILE is the name of the CGI script and will
** typically look something like this:
**
**      #!/usr/bin/fossil
**      repository: /home/somebody/project.db
**
** The command name, "cgi", may be omitted if the GATEWAY_INTERFACE
** environment variable is set to "CGI", which should always be the
** case for CGI scripts run by a webserver.  Fossil ignores any lines
** that begin with "#".
**
** The following control lines are recognized:
**
** The second line defines the name of the repository.  After locating
** the repository, fossil will generate a webpage on stdout based on
** the values of standard CGI environment variables.
**    repository: PATH         Name of the Fossil repository
**
**    directory:  PATH         Name of a directory containing many Fossil
**                             repositories whose names all end with ".fossil".
**                             There should only be one of "repository:"
**                             or "directory:"
**
**    notfound: URL            When in "directory:" mode, redirect to
**                             URL if no suitable repository is found.
**
**    repolist                 When in "directory:" mode, display a page
**                             showing a list of available repositories if
**                             the URL is "/".

**    skin: LABEL              Use the built-in skin called LABEL rather than
**                             the default.  If there are no skins called LABEL
**                             then this line is a no-op.

**    files: GLOBLIST          GLOBLIST is a comma-separated list of GLOB

**                             returned verbatim.  This feature allows Fossil
**                             to act as a web server returning static
**                             content.
**
**    setenv: NAME VALUE       Set environment variable NAME to VALUE.  Or
