simplifies versioning of modules #161
* planning suite defines version of sub modules to use in dependency management
* sub modules declare dependencies without explicit version
this allows also to have separate version numbers for sub modules, if needed
* changes version to 4.3 snapshot - towards next milestone

  it is not possible to specify non default names for the ear file as the currently used WTP plugin has a bug (https://bugs.eclipse.org/bugs/show_bug.cgi?id=340918)

* planning suite ear archive for first deployment can now be built by passing the additional parameter -Ddatabase.schema.generation=create (fixes #164)
  (refer to README.md)

bugfixes and test setup
