Making Module::Build less noisy?

What do people think about quieting more of the messages that
Module::Build prints to the terminal?

For example, there tends to be a lot of "checking this... looks good",
"checking that... looks good", "Deleting this", "Removed this", etc.
type messages.

I think we should try to make the overall Module::Build experience
pretty quiet by default and only spew process messages if --verbose is
true.
