Reverted back to putting default implicits for Equality and EqualityConstraints into
scope rather than in the companion object, since it had the problem with 2.11.0-M3 or so.
Renamed RunnerSuite to RunnerSpec. Wow, probably one of the oldest test classes in the project. And started
handling reminder args.
Finished parsing reminder args.
Cleaned up params to string, print, stdout, stderr, file, and html reporters, both
at the constructor sites and the call sites. Added comments for the next step, which
is adding the new reminder params to all the string reporters.
Pass four reminder args to string reporters. Along the way refactored several
call sites to one arg per line to clarify diffs.
