Configuration XML is added with SSL as sample use-case.
A 'desc' attribute can be used to describe the fields,
and another 'type' to help define the corresponding data
type in the code.
Since Poco allows accessing group nodes (that have the
same name) by index, order can be preserved.
SSL initialization refactored and cert/key file
paths moved to the config file.
