Add ability to change target in CollisionList

[GoogleCodeExporter]

Right now, you can only specify the target for a CollisionList in the 
constructor.

It would be helpful to be able to change the target of a CollisionList after 
the instance has been 
created.

Please add a target property to CollisionList.

This would be useful when you need to do multiple 1 to many collision checks, 
where the many 
are the same for each check (although the 1 is different).

This would allow you to reuse the same CollisionList instance across multiple 
one to many 
checks.

You could possibly use CollisionGroup for this, but that is not always as 
efficient:

1. it may do unnecessary checks, if you dont care that some items hit others.
2. the same items may appear in the collisions array, making it more difficult 
to work with them 
(i.e. removing colliding items from the display list).

I'm happy to report that this ability already exists.  You can change the target
using the CollisionList's swapTarget() method.  Pass it the new target you want 
and
it's done!  You can read about it in the documentation here:

By the by, I'm a big fan Mike.  :D  If there are any open seats at Adobe for the
Flash team, drop me a line?  Pretty please??  ;)

Awesome. That is exactly what I was looking for.
