OpenCLArray is no longer templatized and doesn't provide a host buffer.  This is in preparation for adding mixed/double precision support.

NonbondedForce::updateParametersInContext() is more tolerant about what changes to exceptions it allows

Variable time step integrators correctly report the size of the last step taken.  Also improved accuracy of integration unit tests.

Implemented per-DOF uniform random numbers for OpenCL.  Also fixed some bugs in getting and setting per-DOF variables.

On Fermi, store forces as 64 bit fixed point and update with atomic operations.  Also various other minor optimizations.

Refactored ForceImpl, lots of KernelImpl subclasses, and other related classes to avoid redundant calculations when requesting a State with both forces and energies
