New Addressable::URI throws exception on #scheme=

[jordansissel]

Howdy! Thanks for the code. Found a bug I think.

    >> a = Addressable::URI.new
    => #<Addressable::URI:0x1226874 URI:>
    >> a.scheme = "http"
    Addressable::URI::InvalidURIError: Absolute URI missing hierarchical segment: 'http:'

If I set a host first, this works:

>> a.host = "foo"
=> "foo"
>> a.scheme = "http"
=> "http"

It's not really a bug. Addressable needs to validate the URI after every modification to it. 'http:' is not a valid URI. Rather than create the URI piece-wise, use the constructor and hash notation:

a = Addressable::URI.new(
  :scheme => "http",
  :host => "foo"
)

Ahha, ok this makes sense.
