Support for serialization of Integrator base class, and two derived classes: LangevinIntegrator and VerletIntegrator. Also added support for python serialization via a single deserializeIntegrator()

Implemented setting random seed for reference platform, as well as adding it as an option to BrownianIntegrator and AndersenThermostat.

Implemented dynamic loading of platforms from DLLs.  Also fixed a lot of compilation errors and warnings under Windows.

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