Target platform become the integration stack directly

* Rather than attaching a local version of the IS-TP as komodo.target to
  the mvn build, use the IS-TP directly.

* The komodo.target is no longer stored in version control but can still
  be generated using the build script in the target-platform directory. Its
  primary function becomes the vehicle for loading the TP into eclipse.
Fixes empty block statement errors

* Adds either comments or code to empty blocks identified by compiler
  errors.
