Title: don't require Reason-Phrase

Some web sites return response without Reason-Phrase, and in this case twisted throws exception.
According http/1.1 rfc http://tools.ietf.org/html/rfc2616#section-6 - "The client is not required to examine or display the Reason-Phrase."
If Reason-Phrase is not present we just return standard one from mapping.
