This has a few benefits over the old system:
* We don't have to copy our Maven, Java, and Actionscript settings to every project
* Maven dependency fetching uses a cache in dist until clean is run instead of checking for
snapshots on every build
* Building aslibs no longer needs to generate a configuration file, which grows confusingly stale
* Nailgun can be used to run mxmlc. This cuts actionscript compile time in half. It can also
generate a script to call nailgun, which avoids the few seconds of Java startup required to run Ant.
This means we're using Flex 4 to compile naryalib.swc now, but we released a 1.7 recently. Any
projects wishing to stay out of Flex 4 land can pin to that.
If this goes off without too much turbulence, I'll migrate our other projects in a couple days.
