Fixed getTime() calls in _openMMBrookInterface()
Based on Sherm's suggestions:
changed '#ifdef WIN32' to '#ifdef WIN32 _MSC_VER;
reordered include files so that system files after OpenMM files
all include files should be C++ files now (as opposed to C files (<math.h> -> <cmath>

License header changes; force duplication factor to 4; fixed potential problem w/ Shake -- if no constraints, pgm crashes

Fixed setting of runtime in BrookPlatform() constructor (constructor w/o args):
if 'brt_runtime' env variable not set, then
internal 'runtime' variable was NULL -- this led to a fault when _setBrookRuntime() was called

Commented out static platform variable, which may have caused initialization problems
Some of the Brook tests now succeed on my computer for the first time.
