#103 Stress tests use counts from build.xml

[David Jencks]

I've changed the stress tests to use threadcount,
iterationcount, and beancount from the build.xml files.
You can set these in a local.properties file like this:

### Test properties

junit.timeout=120000
jbosstest.threadcount=2
jbosstest.iterationcount=2
jbosstest.beancount=2

You may want to use such small values until the tests
all work with these small values.
