[webkit-dev] Place For new Core Module

[Adam Barth]

It's unclear to me how these contributions would further the project goals:

http://webkit.org/projects/goals.html

The closest goal seems to be the following:

[[
Web Content Engine
The project's primary focus is content deployed on the World Wide Web,
using standards-based technologies such as HTML, CSS, JavaScript and
the DOM. However, we also want to make it possible to embed WebKit in
other applications, and to use it as a general-purpose display and
interaction engine.
