Add Fusion framework to vault for installation

[chrisclaydon]

The web tier requires the Fusion framework, which must therefore be installed along with it.

This submission will add a snapshot of all the Fusion source files, plus a pre-built version of the generated build folder.

This is an intermim measure. Once Fusion has its own public SVN site, we will likely change the process to extract a specific version from a specific branch in that vault, and generate the final framework files as part of the build process.
