Feature: Expectlist

Avoid using colors in names

I received feedback that colors were problematic.

To address this, I've add support for:

• expect <=> whitelist

I've made this the primary term and am offering the old one for backward compatibility (along w/ making PRs to existing consumers to migrate).

In some ways, expect is actually more accurate as the action tries to prune the list of things which are no longer necessary.
