Adding 5 new files required to build under Cygwin or LinuxMint. These files were originally supplied by Luminary Micro (now Texas Instruments) and are freely available from their website. When building for the target hardware in the Motor project, the current files should be used and are not supplied here or with the Motor project. These files are essentially stubs that allow the build to proceed. No code is actually called in them.
The Makefile was also modified to pick up these files during the build. Also, executable names had a .exe extension added so they would run under Linux. Sorry for the Window nature of these names.

In the interpreter, removed unused flex/bison code that we were going to use but have since abandoned in favour of our own small parser that reading incoming symbol and statement packets.
