* URL dependency was removed from session handling code. URL object
was only needed to get session key from client request. This was
moved somewhere else to achive better code reusability.
* Added URL parsing functionality that can be used without URL object.
first release of ShellInABox that supports an AJAX interface
instead of the original Java applet.
