Title: Fix #490, #452, #431, and other things

* #490: warn when `*_PROTOCOL` is a non-class
* #452: Print job flow ID to stderr on error
* #431: `combine_cmds`: `shlex.split()` doesn't get along well with unicode

As well as:

* Fix `$HADOOP_HOME` test case to pass if you haven't set `$HADOOP_HOME` on the test machine
* `tests.quiet.no_handlers_for_logger` correctly restores the `propagate` attribute, resulting in less log noise
