Enhancement request - ability to add the current module somewhere on the slide

[greg-hutchinson]

I have just started using Gitpitch and really like the ability to organize the slides into sub-modules. I am currently using it for some training slides. What I would like to be able to do is to automatically include the module name on the slide somewhere. This is useful so that the students remember which module they are currently in so that they can relate the current slide to this concept. My first thought was to use the footnote in the PITCHME.yaml files, but only the root PITCHME.yaml is read. If it would be possible to have all the attributes in the individual PITCHME.yaml dynamically override the root file, this might be useful for other scenarios as well. Then this request would be the same as #277 .
However, I am just interested in the sub-module name for now.
