TMI: Miscellaneous

Today: meetings, trying my best to get a miscellaneous pull request (collecting together small changes, including enabling some more rustpkg tests) to go through, working on workcache some. I changed the freshness function for files so that just changing the datestamp, even without changing the contents, counts as changing the file. But, I realized that I'm not declaring any discovered dependencies as inputs to workcache; only the files in the main package we're building. That won't do. Fixing it tomorrow.
