TEIIDDES-1696: Upgrades to using 4.1.0-beta2 parent pom

* Builds designer with tycho 0.18

* 4.1.0 integration stack remains the same so no change to the target
  platform.
Updates target platform to replace locus version of apache poi

* Version of apache poi in locus is 2.5.1 which is oooold. The version in
  orbit repository is 3.9.0.

* Better to use orbit's version since its cleaner and provided rather than
  packaging and maintaining it ourselves.

* Updates target-platform pom to use CR2 release of target-platform-utils

* Orbit repository added to target as its supplied new version of poi
