This PR increases the spotbugs rank, where higher rank means less "important" bug. Our current rank is 3, and I was able to get us up to rank 7. Ultimately this PR will serve to tighten our static analysis testing for future code, steering us away from bug-prone patterns.
For ranks 7 and below, I fixed the ones I could, and suppressed the ones that did not seem worth the effort. Some unused methods have been deleted.
At rank 8, the number of bug-prone detections skyrockets. I started trying to fix them, but ended up doing much more suppressing (i.e., telling spotbugs to ignore certain bugs) than actual fixes; eventually I gave up, since many of them did not seem too important. I left my rank 8 suppressions commented out in the spotbugs configuration file, in case anyone wants to continue this effort.
