Added the option to print the request

Browse Source 
It is now possible to print any combination of the following
request-response bits:

    - Request headers (H)
    - Request body (B)
    - Response headers (h)
    - Response body (b)

The output is controlled by the --print / -p option which
defaults to "hb" (i.e., response headers and response body).

Note that -p was previously shortcut for --prety.

Closes #29.

String specifying what should the output contain. "H"
stands for request headers and "B" for request body.
"h" stands for response headers and "b" for response
body. Defaults to "hb" which means that the whole
response (headers and body) is printed.
--headers, -t Print only the response headers. It's a shortcut for
--print=h.
