TPE sec 1

As expressed on the call, I propose to drop the current introduction. 
The TPE is about technical building blocks.

proposed new text:

This document contains the technical building blocks for the DNT 
standard. This specification defines the technical mechanisms for 
expressing a tracking preference via the DNT request header field in 
HTTP, via an HTML DOM property readable by embedded scripts, and via 
properties accessible to various user agent plug-in or extension APIs. 
It also defines mechanisms for sites to signal whether and how they 
honor this preference, both in the form of a machine-readable tracking 
status resource at a well-known location and via a "Tk" response header 
field, and a mechanism for allowing the user to approve exceptions to 
DNT as desired.
