changed the type of the isAlchemical Cuda array to float, which is needed for the CudaNonbondedUtilities.addParameter method to work; the TestCudaAmoebaVdwForce now passes for its current set of tests, but new tests are needed to check the softcore behavior

Rough draft AmoebaVdwForce Cuda code; next steps are to add CUDA kernal compilation support for USE_SOFTCORE, VDW_LAMBDA, VDW_SOFTCORE_POWER, VDW_SOFTCORE_ALPHA, and per particle isAlchemicalI / isAlchemicalJ flags

AMOEBA vdW softcore is propogated through the Reference platform; pending some feedback adding it to the CUDA code can begin

Fixed an edge case bug for Gyrcuk Radii. If the radius (ri) of the atom being descreened is larger than sum of the separation distance (r) and scaled descreening radius (sk), then there is no descreening. This could happen for carbon atom (ri ~= 2) engulfing its bonded hydrogens (sk < 1).

o Variable renaming in multipole electrostatics code, to avoid confusion.
o CUDA test case only runs finite difference test for the double precision test.

Modified dummy cuda getLabFramePermanentDipoles from getSystemMultipoles to getInducedDipoles Implementation

Added LabFramePermanentDipole function to the cuda kernels files, but it currently works as getSystemMultipoleMoments
