[feature request] Follow gitignore files

[pluja]

Is your feature request related to a problem? Please describe. When sending files, there are sometimes that I don't want to add folders (i.e. node_modules)

Describe the solution you'd like Following a .gitignore file would be a great solution. Maybe adding a --gitignore flag or something like this, that would enable following the gitignore so the files and folders specified there are not sent.
