[pdfmod] Inserting another document using menu/toolbar

[Julien Rebetez <julien fhtagn net>]

Hello,
When I first launched PdfMod, I searched for 2 minutes how to add pages 
from another file. I finally found out that you had to drag the file 
from nautilus, but I think this functionnality should be present in the 
menu/toolbar.

The attached patch adds this to the "Edit" menu and to the toolbar as well.

Regards,
Julien
