Version 0.5.3

This release includes the following changes:
- Changed compression. Packets were compressed with zlib wrapper as described in RFC 1950. But the IRISLWZ RFC 4993 specifies to use RFC 1951, which is the raw deflated datastream without any header. This is a bug not only in this client, but also in DENIC's DCHK server and java client, which will be fixed soon.
- CLI: new parameter "--rfc1950" to use the zlib-wrapper in compression as it was done before. The new default is now to use the raw deflated datastream without zlib-wrapper.
- Lib: new function "irislwz_UseRFC1950", to tell the library to use the zlib-wrapper, as it was done before. The new default is now to use the raw datastream without zlib-wrapper.
- GUI: added a new checkbox to switch between wrong RFC 1950 and correct RFC 1951 compression implementation.
- Constructor of CDchk initialise the class to send uncompressed requests
- Fixed a memory leak in irislwz_Talk
- Enhanced dchk.m4 autoconf macro

New Version: 0.5.2

I was very busy this weeknd and have started to write a generic DCHK server. For testing purposes I have added a few new functions to the client and also fixed some Bugs:
* Fixed a bug in the XML parser</li>
* Fixed some typos in the configure script
* Added new functions for testing purposes. The functions can be used to manipulate the request packet before it gets send to a server. Use them to test a server's behavior of corrupt data.
* A response with transactionId 0xffff is not treated as error anymore
* Fixed a wrong path in Doxygen configuration file
* CLI: renamed flag --ac back to --dac. The rename in the last version was completely stupid, and in fact the CLI interpreted the flag as to not send compressed requests...

DENIC has launched it's DCHK service

On 23. September 2008, the german registry DENIC (http://www.denic.de/) has launched the first DomainCheck (DCHK) service worldwide. DENIC is the first domain registry to break new ground in this field: It plans to substitute the high-performance Domaincheck (DCHK) for the known information service ''whois'' in the medium term. The DCHK specification (RFC 5144), published at the start of 2008, is based on the IRIS standard (Internet Registry Information Service, RFC 3981), which needed several years of intensive work to be established. As a member of the IETF Working Group CRISP (Cross Registry Information Service Protocol), DENIC's employee Marcus Sanz took a leading role in formulating IRIS.
