Patch: java/awt/Event.java

[Bryce McKinlay <bryce at albatross dot co dot nz>]

This is an almost complete implementation of the AWT 1.0 event class. I
wrote it a while back with classpath in mind, but I never contributed
it. Now that we're not using classpath AWT it makes sense to contribute
it to libgcj instead. ok to commit?

regards
