sd signature line: include shape in the appearance widget

With this, finally the following works:

1) file -> digital signatures -> sign existing pdf

2) file -> digital signatures -> signature line

3) draw a rectangle

4) popup appears, select signing certificate

5) click on the "finish signing" button on the infobar

The resulting pdf will have a signature on it, together with the pdf
export of the signature line shape.
