Split quickstart code sample into three, since it shows different things. Added HTTP request to quickstart examples.
Fixed simple GET request example and added simpler example that doesn't use a request object
Moved request object example to quickstart section
Fixed a number of issues with code examples
Added paragraph about adapter configuration, and added SSL example
Removed the long list of Zend\Http\Client methods which I don't think add anything to this page, but make it unecessarily long
