Add EMailPrintConfigHeaders.

This splits the print dialog's "Headers" tab into a separate widget.

EMailPrintConfigHeaders takes an EMailPartHeaders and displays its print
model, which is a representation of all message headers (except subject)
with an on/off flag for each.  The headers can be toggled and reordered,
and the changes are written back to the print model.

During printing, EMailFormatterPrintHeaders uses the same print model
to determine which headers to show and in what order (except subject).

This approach is much saner than the old method, which was trying to
manipulate WebKitWebView DOM directly to toggle and reorder headers.
This approach also happens to work, whereas the old method did not.
