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.
