I've gone ahead and committed something that does Bryan's suggestion:  
generates a /META-INF/ file and outputs the  
current Subversion revision number to it.

The org.apache.openjpa.conf.OpenJPAVersion class will load that file  
and store it in the static "REVISION_NUMBER" field, as well as output  
it when the main() method of that class is run.

It's not perfect, but it's better than not having the information at  
all. In the future, we might want to think about writing a Maven  
plugin that does this a little more smoothly.
