[RFC] Module::CoreList removed modules functionality

It has come up on a few IRC channels regarding Module::CoreList and corelist
and the fact that whilst one can see when a module first entered core
and all the perl versions a module is included with, there isn't a mechanism
to indicate when a module departed from core.

( Well, there obviously is if you want to play with %version yourself ).

I've come up with two new functions to compliment first_release() 
and first_release_by_date():

removed_from()
removed_from_by_date()

Which return the first perl version from which a specified module is removed.

I considered that this was more useful than a last_released() type function.

( Not to say we couldn't have last_released() as well ).

I've amended the venerable corelist utility as well so it produces this type of
output now:

$ corelist ExtUtils::MakeMaker::bytes

ExtUtils::MakeMaker::bytes was first released with perl v5.6.2 and removed from v5.10.1

$ corelist File::Spec

File::Spec was first released with perl 5.00405

The main question is do the function names make sense?

Many thanks in advance,
