Initial Commit

[glgorman]

This is an initial commit of the code base for the Propeller Debug Terminal. To use the oscilloscope features and other graphical debugging features you will need to include a library called "Frame Lisp", which has not yet published, as it is being updated for Unicode support, and undergoing further debugging. This will be remedied in a future update, "real soon now." In the meantime, the boilerplate needed for MFC based document view architecture is functional to the point of being able to upload binaries to the propeller P2 hardware, and interact in text mode via keyboard and mouse if desired, as well as create and manage multiple debugging windows. Port speeds of up to 2Mbits/sec. are known to be reliable with the tested hardware.
