Update Geneticd

Gcc 3.2 does not compiles Geneticd anymore; also, latest linuxthread implementation cured some flaws that Geneticd relied upon. For this reasons, I am updating geneticd (and since I am there, restyling it a little).
A gcc 3.2 complilable version is already on cvs, while I have just developed a library that uses abstract posix thread models; A new complete version will be up soon.
