Add option to the webapi to not render the raw materials and build time

[tzwaan]

Add a boolean option (default false) to the webapi to turn off the rendering of the raw materials and the build time, essentially only generating a picture of the blueprint.

Hi tzwaan!

Check out this comment: #126 (comment)

If you set "show-info-panels": false, it will not render the side panels.

Oh great, it already exists.

I guess there needs to be some proper documentation written for blueprintbot. After I'm done with this project, I'll see if I can help cleaning up the documentation and build-process of blueprintbot so people don't need to message you directly.
