Replace 'Testing JJB' with the term 'Test Mode'

The term 'testing' is overloaded.  I thought it meant running the actual
JJB tests instead of running the JJB application.  I think a good way to
distinguish the two is to use the term 'test mode' when it's in the
context of running the JJB application with the 'test' parameter.
I've already been using the term 'run in test mode' quite a bit in
my JJB reviews to distiguish it from the actual JJB tests.

Clarify configuration and job definition

The docs was a little confusing in that used a single term 'configuration' to
referred to both the JJB global configuration and the job definitions.
This change clarifies that by changing 'configuration' in a few places
to 'job definition' to make it less confusing.
