Summary: Variable task breaks on ant 1.6.1

Initial Comment:
The var task seems not to work correctly using ant 
1.6.1. The "object rape" method of stealing 
the "properties" field from the Project class is no longer 
valid since this had moved to a PropertyHelper class.

This breaks its functionality. A.o. the example in the 
documentation that does <var name="x" value=""/> no 
longer works; the <format/> task later on cannot use 
the value anymore.

And: the documentation of the task speaks of a 
(handy) "unset" attribute of the task, but this is not 
available.

I'm having a strange problem with this task. I've copied a
simple build file that shows the problem to the end of the
message.

I don't know if I'm doing something wrong or if this is
supposed to be the correct behavior, but it's not what I'd
expect from the task description.

It involves calling other targets in the same project using
"runtarget" and changing the value of some property used by
that target. Within the same task the values of "x" are
changed, but the target called by "runtarget" always sees
the first value assigned to "x".

========= begin build.xml
<project name="bug" default="test">

	<taskdef resource="net/sf/antcontrib/antcontrib.properties">
		<classpath>
			<pathelement location="../ant-contrib-1.0b1.jar"/>
		</classpath>
	</taskdef>

	<target name="test">
		<var name="x" value="6" />
		<echo>${x}</echo>
		<runtarget target="callthis" />
		<var name="x" value="12" />
		<echo>${x}</echo>
		<runtarget target="callthis" />
	</target>

	<target name="callthis">
		<echo>From "callthis": ${x}</echo>
	</target>

</project>
========= end build.xml

the <var name="x" unset="true"/> command gives an error on 
ant-contrib-0.6: 

The <var> type doesn't support the "unset" attribute.

This would be a handy thing. Seems the attribute is not 
available for this task. Problem still occurs.

This is more a documenation issue than anything.  Setting the 
value to "" no longer allows the format task to set the value.  
I have changed the example to use unset="true"
