SFDC importer plugin has copies of lots of 3rd party jars that maybe should be in sep plugins

I noticed that as of MS1, the SFDC importer plugin contains a lot of copies of third party jars, most Apache Axis/Apache Commons stuff. In many cases, these same jars are also in the com.metamatrix.modeler.dqp_5.5.3 plugin since they are also needed by the SFDC connector. I also noticed that some of our other Designer plugins that use external jars put those jars in their own plugins, and import the plugin, rather than putting them in the same plugin as our own code.

We should consider pulling these jars out of the SFDC importer plugin and putting them in their own plugins (which the SFDC importer plugin can then import), or simply importing them in the SFDC importer plugin from the DQP plugin.

The same problem exists to a much lesser degree in the WSDL importer (just the commons-codec-1.2.jar is duplicated in that one).
