Installers and Ant

[Alex Harui <ah...@adobe.com>]

Hi,

I checked into flex-utilities the beginnings of a new library that could
eventually allow us to emulate most or all of Ant in AIR.  The plan is to
use this in the Apache Flex Installer going forward.  IMO, if we can
script the install in a .xml file, then the Apache Flex Installer will
need many fewer releases, hopefully only to make bug fixes, and that will
simplify the release process for the various release packages we're going
to be having going forward such as the Flex SDK, Falcon, and FlexJS.

Please take a look and let me know if you like it or not.  Each XML tag is
represented by a separate AS class so it should be easy for folks to pitch
in with new tag support.
I've only implemented a few tags so far.  Many more are needed.

Thanks,
-Alex
