In calcForces() kReduceBornSumAndForces kernel is not needed since Born radii/Obc chain term now calculated prior to calculation of forces
Modified kCalculateObcGbsaBornSum kernel loop to match that in kCalculateCDLJObcGbsaForces1; Born sums are zero w/o mods

Optimization to constraint algorithm: skip the last iteration as soon as we see that all constraints have converged.

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

Eliminate some VC++ build problems via the usual expedient of explicit casts from unsigned to signed and from double to float. TNT Arrays apparently can't be indexed with unsigned because VC++ finds something ambiguous then above their operator[] methods.

Added Platform::getDefaultPluginDirectory().  Plugins are now installed into .../openmm/lib/plugins.

(2) Changed erfc.cpp to a header file which defines missing erf() and erfc() as static functions when using VC++ but otherwise does nothing.
(3) Replaced all nonstandard uses of real() and imag() methods as lvalues; instead work directly with the complex values.
(4) Fixed a bug in TestFindExclusions which was caught by VC++'s extensive STL debug mode self-examination.

There are still problems in hilbert.c and not all CUDA tests pass.
