Subject: GTK3, Webkit2 support for epub

I added the code to make it possible to build Atril with GTK3 and webkit2. Everything runs fine with both GTK3 and GTK2. The find module for epub was also tested and changed. Now I shall first attempt to fix some Glib errors, and the problem of the temporary directory not getting deleted, that arose when I stabilized the thumbnails.
