Implemented the Ewald summation method in the reference platform. Preliminary cuda prototype is included.

removed redundant qualification ‘ReferenceForce::’ on member ‘getDeltaRPeriodic’ to get compile on linux

1) Added DLL export macros to many classes; enough to get tests to compile
2) Cosmetic changes to reduce warnings in Visual Studio:
   a) change many "for (int i ="... to "for (size_t i ="... to avoid unsigned mismatch warnings
   b) included many explicit static_cast<OpenMMReal>() casts to document places where double->float conversion warnings occur

Added INCLUDE(Dart) to OpenMM CMakeLists.txt

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

Continuing to implement ReferencePlatform (implemented kinetic energy calculation and LangevinIntegrator)
