Fix the build

This does the following things:

* Declares the missing version of Trainable_Segmentation.

* Adds an enforcer rule to ignore the imglib2-algorithm /
  imglib2-algorithm-gpl class clash of HyperSphereNeighborhood
  (to be fixed in the next release of those libraries).

* Adds an exclusion on jama:jama to the Fiji_Archipelago dependency.
  (The real fix there will be to release a new mpicbg that depends
  on the right GA for jama: gov.nist.math:jama.)
