[tz] Palestine DST starts on 2013-03-29

Here's a proposed update to the tz database for Palestine
that takes the comments of Petr Machata and Steffen Thorsen
into account.  This supersedes my earlier proposal in
<http://mm.icann.org/pipermail/tz/2013-March/018813.html>;
that is, it contains a single combined patch.

I'd like to push this out the door fairly soon, since the
current time stamps are wrong for Palestine.  I'll also
propose a simple patch for the Macquarie country-code
bug.  The Australian abbreviations need more review so
I'd like to defer them until after the next release.

	Palestine observes DST starting March 29, 2013 (reworked).
	Thanks to Steffen Thorsen, in
	<http://mm.icann.org/pipermail/tz/2013-March/018812.html>.
	An earlier version of this patch was mistaken.
	Thanks to Petr Machata for reporting some of the bugs, in
	<http://mm.icann.org/pipermail/tz/2013-March/018814.html>.

	* asia (Palestine, Asia/Gaza, Asia/Hebron): Incorporates the latest info
	from timeanddate.com about Palestine.  When combined with the previous
	(incorrect) patch this incorporates the following changes for Gaza and
	Hebron:

	  The spring 2008 change in Gaza and Hebron was on 00:00 Mar 28, not
	  00:00 Apr 1.

	  The fall 2009 change in Gaza and Hebron on Sep 4 was at 01:00, not
	  02:00.

	  The spring 2010 change in Hebron was 00:00 Mar 26, not 00:01 Mar 27.
	  timeanddate.com's table says 02:00, but the text at
	  <http://www.timeanddate.com/news/time/gaza-and-west-bank-dst-2010.html>
	  says 00:00.

	  The spring 2011 change in Gaza was 00:01 Apr 1, not 12:01 Apr 2.
	  timeanddate's table says 00:00, but the text at
	  <http://www.timeanddate.com/news/time/west-bank-starts-dst-2011.html>
	  says 00:01.

	  The spring 2011 change in Hebron on Apr 1 was at 00:01, not 12:01.

	  The fall 2011 change in Hebron on Sep 30 was at 00:00, not 03:00.

	  From 2013 on, Gaza and Hebron both observe DST, with the predicted
	  rules being the last Thursday in March at 24:00 to the first Friday on
	  or after September 21 at 01:00.

	* asia (Palestine): Add rules for 2011 on, to simplify Gaza and Hebron.
	Adjust to recently announced changed.
	(Asia/Gaza, Asia/Hebron): Use adjusted rules.
