Use EDITOR and PAGER environment variables to edit and view respectively

[zummenix]

Currently, broot creates a config file with edit and view tools predefined. I think, for most users the default/expected behaviour would be to use tools set in EDITOR (with fallback to vi?) and PAGER (with fallback to less?) environment variables.

The problem is not so many users have those variables defined, which means you need to ask users to define an editor in the config anyway. I didn't see any obvious way to make that clear for users.

Even xdg-open is rarely very relevant.

To clarify, the behavior I'm talking about is: when invoking an edit use tool defined in config; if not defined, fallback to EDITOR; if the variable is not set, fallback to vim. The same for open. I don't think it requires more explanation in the docs.

P.S: with current defaults edit doesn't work for me, because I have neovim installed in another path.
