Updated Build Instructions
Updated Build Instructions

Added better download and build instructions for the Avis client and router.

For the OpenMAMA build it is necessary to specify --with-avis to build the Avis
bridge, and it is also necessary to invoke generateBuildFiles.sh prior to
building source from a cloned git repository.
