Fork of HTTPClient by Vincent Wochnik

More recent changes - added iCal processing.

Derivative of a derivative, however this one works when it comes to supplying Basic authorization to access a protected resource. Some additional changes to the debug interface to clean it up for consistency with many other components I have.
