Import the QtWebKit documentation

This places the documentation in separates .qdoc files with the original
license header preserved. We don't want to contaminate our implementation yet
just for the documentation, so keep it separate for now.

New documentation that isn't attached to the QtWebKit LGPL license should go
inline in the code as usual.
