- Remove API change for AmoebaAngleForce so it goes back to only taking degrees.
  Handle conversion via a pythonprepend (since stripUnits is done in C++ now).
- Do the same thing for TorsionTorsionForce, since angles are in degrees again
- Add AmoebaVdwForce and AmoebaWcaForce tests

angles are in degrees (unlike *every* other angle force out there), and
stripUnits automatically reduces all angles to radians if they come in with
units.

The approach here is to *slightly* change the API, so that
AmoebaAngleForce.addAngle interprets input angles <2*pi as radians, and >2*pi as
degrees. This is heuristic, but should work in every case out in the wild so
far.

I've also updated the documentation to reflect this behavior, and fixed the
units attached to the return value of AmoebaAngleForce.getAngleParameters() to
return degrees instead of radians.

from all .cpp and .h files.

Moved AMOEBA include files to plugins/amoeba/openmmapi/include/openmm to be consistent w/ outlay other plugins, ...

Modified the API for lots of classes so that the number of particles/bonds/etc. need not be specified in the constructor.

Modified the initialization order of ForceImpls to prevent them from trying to initialize themselves before the Platform had been chosen

Continuing to implement ReferencePlatform (implemented GBSA kernels, added test case for SHAKE and fixed some bugs in it)
