Conda nbdev package is severely outdated, and and its script don't work on Windows

[jnareb]

The "Installing" section of nbdev homepage documentation (https://nbdev.fast.ai/#Installing) says:

nbdev is on PyPI and conda so you can just run pip install nbdev or conda install -c fastai nbdev.

However the conda version is severely outdated as compared to PyPI version: 0.2.40 on conda, 1.1.6 on PyPI.

Additionally the scripts provided by conda installation does not work on MS Windows:

> nbdev_clean_nbs
Program 'nbdev_clean_nbs' failed to run: No application is associated with the specified file for this operation
At line:1 char:1
+ nbdev_clean_nbs

Note that for clean nbdev installation beside uninstalling nbdev installed via conda, one needs to uninstall also fastcore and fastscript packages installed as dependencies by conda before installing nbdev via pip.

nbdev latest is always automatically uploaded to anaconda:

https://anaconda.org/fastai/nbdev

MS Windows is not currently supported - sorry about that.

@jph00 : I wonder why while the current version of nbdev is 1.1.11, conda install -c fastai nbdev installs version 0.2.40. while pip install nbdev installs 1.1.6 (on MS Windows, using Anaconda Python distribution)...

It would be nice to have the fact that nbdev on conda is not supported on MS Windows explicitly said in the documentation.

OK I've added that information.
