Expand Process Versioning

It would be nice if Riftsaw supported more than a single digit. Many people use maven which has a major.minor. or even a -##.##.## versioning.
Also documentation could be better to explicitly show the format that the bpel process jar should be. I had someone trying to deploy TestBPEL-2.0.1.B.jar, which has 2 problems, one is the B gives a NumberFormatException and also the .0.1 is ignored.
