I used the current sources ( with the new comments), and reimplemented
all changes.

The current version doesn't have anything related with the other proposals,
and is functionally equivalent with the old ProjectHelper - except it's
cleaner ( all private and SAX code moved to the helper imple ).

I created a new package, o.a.t.ant.helper to keep the core cleaner -
other helpers may be commited.

The SAX2 based helper is easy to write, but depends on few improvements
on RoleFactory ( createTask with namespace support, etc ).
I'm working on a new implementation of the task factory, with support
for data types and other roles - but that's another story.

Most of the functionality in Main is moved into AntBean ( all public/protected
methods are now wrappers around AntBean's functionality, for backward compat).

Same in ProjectHelper - again, for backward compat the public/protected functions
are unchanged, old code can still call the old methods and get similar behavior.


In TaskAdapter - few improvements ( still more to go ) to allow a program
to control tasks that are in a child loader. That's extremely important to
get ant embeded and controlled in a programatic way ( Project may create
tasks in a child class loader, so casting will fail - the only way
to use them is by using introspection ). I've also added the ability
to 'adapt' beans that have multiple methods, not only execute()

Please review, try, let me know when I can commit it.
