As part of the effort to support lwIP as an app, I've been asked to remove dependencies from the app and have done so. ETHDRVCE is now a standalone library that will be converted to a libload library once it has been tested a bit. The eth driver functions will need to be passed into lwIP by the user.

I ask that anyone with the ability please test this out, and let me know if there are any issues (you can edit main.c to do whatever you want and use wireshark to test). If there are no bug reports in a week; I'll convert it to a libload lib and release it.
