Proposal to export the builded request

[jgomo3]

After finally excecuting a request and checking is good, it would be nice to export that request in different formats, like httpie, curl or raw, in order to share it with others or for documentation.

For now, you can export HTTPie command using the httpie command:

> httpie post
http POST http://localhost

cURL is on the roadmap. I also consider adding raw format.
