Context into the platform rather than hacked into getRandomNumberSeed...

Someone please check this.

Platform specific header files get installed.  This allows plugins to be built with just an OpenMM installation, not a full source tree.

Tony's changes to error handling in the CUDA platform so it throws exceptions instead of calling exit()

Moved SFMT into libraries folder, and restructured it to allow multiple independent random number generators

Use a consistent (and more accurate) value for electric constant everywhere.  Also cleaned up handling of constants and units in various places.

Incorporate Normal Mode Langevin openmm code from Chris Sweet as a plugin.  (compiles on windows, but no actual testing done)

Free energy plugin added
Plugin will not run w/ Obc or GB/VI forces unless line 2004 of gpu.cpp (gpu->sim.totalNonbondOutputBuffers  = 2*gpu->sim.nonbondOutputBuffers;) is commented in -- working on removing this constraint
Also unit tests for GB/VI currently fail 

- MingW, where "WIN32" is set by CMake but the compiler is not Microsoft's (should use _MSC_VER) in that case, and 
- in gcc 4.4 which is fussy about some issues that earlier versions were silent about, such as passing a string constant to a "char*" rather than a "const char*".
I also fixed a syntax error in CMakeLists that showed up in the OpenMM workshop for some unknown reason.

Brook is not currently building correctly; I think it has not yet been fully converted to the getTime() interface needed for variable step integrators.

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

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 'return platform' to registerReferencePlatform() -- VisualStudio complained about no return value
Added #include "../sfmt/SFMT.h" to SimTKOpenMMUtilities.h to get 'uint32_t' declaration

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