Auto generate regular expressions / simplify data input fields.

[pkw365]

I have noticed that opensnitch can generate regular expressions on it's own.
As an example rules for appimages.

Why not implementing this for all data input fields ?

Regular expressions are a real pain for "common" users like myself.
Easy to make mistakes or simply to difficult as is the case with appimages.
