add back debug logging
Make Utility.Process wrap the parts of System.Process that I use, and add debug logging to them. Also wrote some higher-level code that allows running an action with handles to a processes stdin or stdout (or both), and checking its exit status, all in a single function call. As a bonus, the debug logging now indicates whether the process is being run to read from it, feed it data, chat with it (writing and reading), or just call it for its side effect.
