TEIIDDES-1734: Upgrade the Target Platform to 4.1.0-beta1

* Upgrades designers to the targeted 4.1.0 platform. As it is only beta1
  at the moment, further upgrades will be required but problems should be
  negilible.

* teiid-designer.target
 * modifies the target for use with new target platform

* *.salesforce/*/MANIFEST.MF
 * Cannot use javax.xml.rpc on its own since it requires the imported
   packages javax.servlet and javax.servlet.http. These were provided in
   the old platform by org.eclipse.equinox.servletbridge.extensionbundle.
 * This is available but no longer depended on and problematic since it
   fakes the export of these packages.
 * Depending on javax.servlet provides these packages and allows the
   bundle and its test fragment to be compiled.
