Dump all generated images to central directory

[tir38]

We want to bundle the generated .png files with our internal documentation. It would be helpful if they were all in a single director, w/out having to navigate through the project to find and move them.

Agreed, I tried to get this done as part of 0.1.0 but could not make it. Rough implementation which copies all scabbard files to build/scabbard/ folder.

I'll create a separate issue to discuss the implementation details and link this there.

oh yeah, no rush. I love what you have so far!
