Generated mdakit reStructuredText files should be put in a subdirectory

[ianmkenney]

The generated Kit documentation is placed in the same directory as manually edited docs, such as about.rst. For development this only creates noise when it comes to version control as each new kit will add a new line in the "Untracked files". I suggest we have generated files put into a kits/ directory, which can then be put in the gitignore.

those files should be autogenerated - they shouldn't ever be kept around - edit: I think I see what you mean, just an empty kits folder?

Yes, when generating the files, the kit/ directory should be created. No need to keep the empty directory around in VC either, basically the same way the _build/ directory is treated which is explicitly in the gitignore.
