properties.

This is not final, of course.

PropertyHelper will implement all property manipulation. Eventually in
ant1.6 the static methods in various places should just wrap and
call this. In 1.6 the property storage can also be migrated to this
class.

It should be possible by a task or embedding application to replace
the whole mechanism - no need for discovery on this one, it can be
done by a task.

The PropertyInterceptor will be used to plug different sources
for the property. I'm thinking to just have tasks/types implementing
this interface automatically get registered - it's the simpler
solution for tasks developers ( I think ).

will replace all optional tasks, using an AntClassLoader to load
( delegation disabled for the optional package ).

Next step is to add a task that adds jars to the loader for optional.
( like junit.jar, etc ).

and supports SAX2 attributes.

In addition, the property substitution has few enhancements: if the
property name is not found and it has a special syntax we'll use the
references to compute a value.

This is work in progress, but the intention is to support dom: syntax
for selecting nodes ( similar with XmlProperties, but using 'life'
DOM tree ) and bean: to use getters on the tasks/objects in the reference
table.

to the first one, and redo the fixes ).

I fixed the inner class problems, fixed the Attributes->AttributeList conversion.

I also turned the processing from 'implicit' recursive to an explicit
stack. The model is identical with the one used by Axis, and it's much
cleaner and easier to maintain/extend/etc.

Again, I can move back to the first one if anyone has a problem with this
change. I think it's a very good one, but may be too much.

Note that it already had dependencies on SAX2 interfaces, but the original
helper worked with SAX1 parsers too. This one will only work with SAX2.

IMHO SAX2 should be the default, and the old one should be kept
around for backward compat or special cases.

The parser is not using the namespace in any way - it'll use the
RoleFactory plugin to allow use of the namespace in task creation.
