Test cleanup

[tburghart]

This started with fixing tests to NOT leave test files all over the place, but it quickly became apparent that many of the tests weren't running at all.

Turn off whitespace diffs by appending ?w=1 (or &w=1, as appropriate) to the URL.

With these changes:

• All tests actually run, and pass.
• A few tests have been added that seemed appropriate.
• All tests write only in /tmp and clean up after themselves.
• All relevant cases of failures that would throw a badmatch are now enclosed in appropriate ?assert... macros.
• The fundamental behavior of the tests hasn't been changed.

Note: This does nothing about the cuttlefish kludge, sorry MvM.

Closed and branch deleted because at least some builders, somewhere, still have issues with slashes in branch names.

PR #240 is the relevant replacement.
