subninja/include support

[George Kulakowski]

I've been experimenting with Blueprints in a setup where there are some 3rd party components with a build system that already produces ninja output. My initial assumption was that writing a Blueprint rule to invoke that 3rd party tool, and then include/subninja the resulting file, would be a practical way to do this. There doesn't seem to be a way to do this right now. I had started on a patch to do so. Before I finish plumbing it through, I wanted to see if I was missing a better way, or perhaps if you would consider it out of the design space of Blueprints.

This ended up not being something I needed, closing.
