Updated examples and snapshot of wrappers to what I think is their final form. Fortran no longer uses a RuntimeObjects structure; instead it passes around an opaque handle directly to the Context.

Fix Makefile to set gfortran flag that allows lines of any length to accommodate the machine-generated Fortran module.

Upgrade examples to track Peter's automatically-generated C and Fortran bindings. These are still using a snapshot of the wrappers, slightly hand modified, but they are much closer to the final ones now. When the automated ones are ready and part of the build, these checked-in ones will no longer be necessary.

Added a dummy argument to constructors in Fortran examples because Mark Williamson's compiler didn't like them with no argument.

Examples: now builds CWrappers as a library; modified C builds to use it; added visual studio project to build Argon example in Fortran.
System.h: addForce() wasn't returning the index.

Checkpoint: added HarmonicBond, HarmonicAngle, and PeriodicTorsion to C Wrappers so these can be accessed from the Fortran Module per Mark Williamson's request for Amber.

- 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.

Added FCPPLIBS variable in makefile to accommodate systems where the fortran compiler needs some extra libraries to link with C++. Also added a Makefile.mac with a possible good library combo.

- updated the Readme file
