RTD not building

[marcelstoer]

RTD silently updated their MkDocs version to 0.17.3. This breaks the docs build

WARNING - Config value: 'theme_dir'. Warning: The configuration option {0} has been deprecated and will be removed in a future release of MkDocs.

Aborted with 1 Configuration Warnings in 'strict' mode!

Currently our rtd-requirements.txt in the root is inactive. Analyze if we still need it.

All good now

Thanks Marcel. I've just checked the dev documentation, and it looks good.

No doubt someone will pick up some typos but if you note there is now a whitepapers section and I've moved the two existing tutorial-style sections on the two file system variants as well as my LCD and LFS papers into this. I was in two minds about adding the LCD paper, but it is relevant because NodeMCU is different from standard and eLua implementations in that we get decent error reporting without paying a 100% RAM overhead.

Sorry for the digression, but the documentation system is seamless thanks to your work 👍

I noted the new section, thank you for that, makes sense to me. You had the LCD/LFS labels pointing to the respective other. I fixed that in 3f396cb.

For the record, the RTD issue: readthedocs/readthedocs.org#4314

Durrrhh. Typical Terry mistake. Thanks for this.
