[PATCH] Background processes in execute task

[Stephane <s....@videotron.ca>]

Hello all,

here attached you'll find a small patch to allow background processes
while executing processes.

It 's my first attempt to participate in ant,
i know what i did works fine but i am not sure about the way i coded it
and if it is respectfull of the ant's coding philosophy .
Please give me some feedBack ! I would enjoy to enhance the way i code
:)

The patch proposes a simple way to lauch task in the background.
I added a property "wait" to the execute task , the property is set to
true by default in
order to respect backward compatibility with the previous API.

The wait property is a Project.toBoolean interpreted one.

Hope this help .
