Building CASA using SCons

I've put together a prototype SCons build framework for CASA, here is a brief description:

The advantages are that it will be hopefully clearer and easier to extend the build with SCons, and also the parallel build functionality can accelerate the process significantly. On the computer I've been using the whole build from scratch takes about 18 minutes
