Remember: from the release 0.7 on you need Java 1.5 to run I2P, SUNs Java 1.6 IS REALLY preferred!

The big merge of different branches (14,800 lines change). Including CPUID changes, jrobin159 and naming service changes. Take care! Now the graphs will crash Apache Harmony, JamVM, and GNU gij JVM due to bugs deep in the GNU graphics libraries.

Lots of small changes to get into a real Debian worth .deb package.
Small graph tweaks, CPUID and libjbigi tweaks, address helper refactoring, more floodfill router, append i2cp version information to get/set date messages, use java SHA-256 instead of GNU one and same for SHA-1.

Come to an end with libjbigi changes! - neverending story is build.
A log of changes, all to be read in zzz forum. Mind: this time the i2pupdate.zip is quite huge as it includes the updated libjbigi files which will reduce CPU load on a lot of systems.
