Let Eclipse add Tests project and added that to Makefile as UNIT_TESTS target for packaging

I'm not sure what the effect this will have on the existing Eclipse project - I suspect
that it is toast.  Nevertheless, you can make UNTI_TESTS from command line and if you
add test files via Eclipse, they all get integrated nicely which is what I was trying for.

This does require that gtest is installed and that the make subfolder has been built.  I
will add a forum post very soon to describe the entire process.
Renamed Eclipse project to freeems-vanilla to match directory name and added relevant contents of .csettings directory

With these changes one can create an Eclipse workspace, create an empty CDT project named freeems-vanilla in it and then git clone
to that directory.  After doing that, and starting Eclipse in that workspace, you will have the complete unit test framework
ready to build and run.
