Have separate Launchers for Paging and Ldp TestSuite

LdpTestSuite no longer holds the main method.  There are now two
different classes that can run the test suite: RunLdpTestSuite and
RunPagingTest

To run, include the -classpath argument to the command line
ie) $ java -classpath <.jar file> <class containing main method> <all
the other parameters...>
