v.1.3.1-WP1.10

Build with winpython 1.10 (2018-01).

This build includes a working version of jupyterLab but comes at the cost of installation only possible in a folder with a full path ~< 37 characters... because the maximum length of file path on windows if about ~260 characters and npm which is the javascript package manager (required for jupyterLab), has a deeply nested folder structure...
