[tz] Haiti on DST

[Paul Eggert]

Thanks for the heads-up.  Here's the obvious patch for this,
which I've pushed to the github experimental version.

This seems high-priority, since it affects today's time stamps,
so I'd like to generate a new tz version soon.

Subject: [PATCH] * northamerica (Haiti): Haiti is using US-style rules this
 year, too.

Assume this will continue.  Thanks to Steffen Thorsen, in
<http://mm.icann.org/pipermail/tz/2013-March/018761.html>.

 # From Arthur David Olson (2012-03-11):
 # The alterpresse.org source seems to show a US-style leap from 2:00 a.m. to
 # 3:00 a.m. rather than the traditional Haitian jump at midnight.
-# Assume a US-style fall back as well XXX.

+# From Steffen Thorsen (2013-03-10):
+# It appears that Haiti is observing DST this year as well, same rules
+# as US/Canada.  They did it last year as well, and it looks like they
+# are going to observe DST every year now...
