Add a port of jflex:

JFlex is a lexical analyzer generator for Java written in Java.
It is also a rewrite of the very useful tool JLex which was developed
by Elliot Berk at Princeton University. As Vern Paxon states for his C/C++
tool flex: They do not share any code though.

WWW: http://www.jflex.de/

I've done some clean up to the submitted version of the port.
