Adam Green / 4DGL

Fixed a few minor issues in 4DGL library Moved pc serial port object used for debug output into 4DGL object itself. Previously it was a global object but its constructor wasn't getting run before the global constructor for the 4DGL object itself which led to an assert in the serial code. I also fixed a few potential buffer overruns that I saw in the code as well.

Moved pc serial port object used for debug output into 4DGL object itself.  Previously it was a global object but its constructor wasnt getting run before the global constructor for the 4DGL object itself which led to an assert in the serial code.



I also fixed a few potential buffer overruns that I saw in the code as well.
