Subject: [PATCH] update of jbigi scripts
- merge mbuild_jbigi.sh into build_jbigi.sh and drop mbuild_jbigi.sh
- make build.sh's tests optional
- try to determine the locations of JAVA_HOME and I2P

+In Debian/Ubuntu, install the the libgmp3-dev package to get the libgmp headers.
Then export I2P=/path/to/your/i2p/install.
Then do 'build.sh dynamic'. This will do a quick build using your installed libgmp library
and then test it and the jbigi in your I2P installation to see which is faster.
