#9 Support for other UML tools.

[jdoxey]

At the moment ActivityScript only supports activity
diagrams with the Eclipse UML plugin. Some XSL needs
to be created for other UML tools.

ActivityScript has it's own XML format for scripts.
For UML tools which create XML (XMI) documents, an XSL
needs to be defined for transforming the UML tool's XML
document into an ActivityScript XML document.
