Make selftest dialogue mutable

In order to support future selectivity of test sets, replace the
immutable tuple of all tests with a dict keyed by test object.
Iterate over a copy of it so that the original is not altered when
tests are eventually removed during runtime. For Python 3.5 and
earlier, use OrderedDict so that test order is explicitly preserved.
