API changes. Client cursor and settings menu.

The following API changes may affect integrators:

    - Settings have been moved out of the RFB.connect() call. Each
      setting now has it's own setter function: setEncrypt, setBase64,
      setTrueColor, setCursor.

    - Encrypt and cursor settings now default to on.

    - CSS changes:
        - VNC_status_bar for input buttons switched to a element class.

        - VNC_buttons split into VNC_buttons_right and
          VNC_buttons_left

        - New id styles for VNC_settings_menu and VNC_setting

Note: the encrypt, true_color and cursor, logging setting can all be
  set on load using query string variables (in addition to host, port
  and password).

Client cursor (cursor pseudo-encoding) support has been polished and
activated.

The RFB settings are now presented as radio button list items in
a drop-down "Settings" menu when using the default controls.

Also, in the settings menu is the ability to select between alternate
style-sheets.

Cookie and stylesheet selection support added to util.js.
