* Changed TWSCharEncodings.CharCode to return ErrorCodePage const rather than 0 for unsupported character sets.
* Fully commented unit.

New web services base class in NsWebServices.UBase along with other new units required to support this class: exceptions, character encoding, URI encoding and URI query string parameters. Modified project files accordingly.
