Hello!

I've made further enhancements in makeJava script:
1) -unsafe option turns off checking if the compiler actually creates
output files. It is necessary until java.awt.widget.* problem is fixed.
2) -batch option puts all files which must be compiled in one command line.
3) -force option turns off timestamp checking. "makeJava -batch -force"
should do the same thing as rebuildLib.
4) Better argument parsing.
5) Exit codes are documented.
6) Support for shells whose "echo" doesn't accept "-n".
7) Many minor renicements.

I send the whole file, because it is not (yet) too big.
