Implemented attach-connector step

- removed old \implementation subdir, replaced with \mm subdir
- this will make it easier to port mmapi python demos
- added socket_names,py, contains hardcoded strings
- added connector.py, this implements the three steps of attaching
connector
- extraFunctions.py now contains drivers for these functions
- updated page7.html to call relevant driver functions
- added VS2012 project/solution
- note: VS2010 project is *not* updated, as I don't have it. So, needs
to have new files added by someone else
- new mmapi.py / pyd, for October 9 build:
