Improve Windows default behaviour #964
Description
A lot of issues are opened for windows regarding the default behavior of navi on this platform.
Mainly regarding that navi tries to work with bash when it is not the default to have a shell such as Bash on a windows install.
We are also proposing to install a default cheatsheet which is better suited for linux environments.
It might also be a good idea to introduce a specific cheatsheet for windows, disable the option to download it or show a warning that it is not meant to be downloaded on this platform.
