[jbpm-dev] jbpm-core --> jbpm-jpdl

[Tom Baeyens]

FYI, while updating the docs, i noticed a serious mismatch.  jbpm-jpdl had been 
changed with jbpm-core.  To prevent confusion, I'm changing the artifactId from 
jbpm-core to jbpm-jpdl.  I still leave the module in directory modules/core.

I have build the installer and run the core test suite.  Now I'll be running full 
test suite: first building, installing and starting jboss and then running the full 
test suite including the enterprise tests.  When that succeeds locally, I'll check in 
and start a hudson build.

Also, the download I renamed to jbpm-jpdl-{version}-installer.jar to be in sync with 
previous namings.
