add sogrep command
This is the new and improved, canonical sogrep command, now with a valid license. The previous version of sogrep had several issues and inefficiencies, and ultimately wasn't really the finished project I wanted it to be. Due to a mistake in communication, I was totally unaware it was in the process of being merged at all, nor that there was a licensing issue, or I would have recommended waiting for both further improvements, and a declaration of license intent; nevertheless, here it is now, and I formally give this over into the GPLv2+ domain.
