Custom headers in Get() request

[danilopolani]

Fix feature #9.

There are two ways to define a custom header:

1. Via the Header() function (suggested if you have to add a few headers);
2. "Massive" add via the Headers variable which is an associative array (map[string]string).

As always the README needs an edit.

Examples

Note: all the examples are generated printing the headers received in a PHP page.

No headers

Code

source, _ := soup.Get("http://localhost/headers.php")
fmt.Println(source)

Output

Headers via Header function

Code

soup.Header("Authorization", "Bearer foobar")
source, _ := soup.Get("http://localhost/headers.php")
fmt.Println(source)

Output

Headers via Headers variable

Code

soup.Headers = map[string]string{
    "Authorization": "Bearer foobar",
    "Content-Type": "application/json",
}

source, _ := soup.Get("http://localhost/headers.php")
fmt.Println(source)

Output

@danilopolani Sorry I've been busy the last few days. This looks good at first glance. I'll be reviewing this sometime later and revert back to you.

This looks good. Make the necessary changes in the README too and it should be ready to merge.
