Date Update

There were newlines missing directly after the content-disposition for text fields.
Changed the User-Agent to something more "official" as certain sites block stange user agents
Moved Cookie and Referer to be above Content-Type. Seems like some servers want the content parts
directly after you specifiy the content header.
