Allow Comparator alias parameter to be a function template.

Now invalid comparators are just skipped without any error messages, it makes it hard to debug, what is wrong.

Please add some test(s).

[FeepingCreature]

Hm. You're right, that's a bad problem.
99% of the time, the comparators just do to!string comparisons. Could that be handled by a built-in helper?

We could add a ready-to-use comparator, but I personally wouldn't like to enable it by default. Default comparison is done with .opEquals, but the .to!string-comparison seems to be too Funkwerk-specific to me. Comparators can be configured once per Mocker instance; so you can just define a custom mocker instance and use it across projects?

[FeepingCreature]

Yes, the problem is that Mocker may have to compare very many kinds of parameters, and there's no nice way to discover what they are other than looking what tests fail.

I wasn't thinking enable-by-default, more like expect.foo().toStringComparator or such.
