ANNOUNCE: DateTime::Set 0.1406

[Flavio S. Glock]

DateTime::Set 0.1406 is in CVS.

- New methods:
  DateTime::Set::map / grep
  DateTime::SpanSet::map / grep
  From a discussion with Andrew Pimlott and Dave Rolsky
- Deprecated methods:
  iterate() marked as "internal"

Version 0.15 will have to wait until I find out
how to deal with backwards incompatibilities:

DateTime::Set versions after 0.1402 break some
DateTime::Event modules, with an infinite loop inside
the "next()" method.
