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.

Fixed a memory leak that occurred during a redirection. Whether the redirection was 1 step, or many, there was a single leak. Fix was to free memory in the destructor.

; Reflowed the source to improve consistency.
