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.
