Build AppImage with gtk3

Browse Source 
This also fixes #92, fixes the opening of the PDF manual under AppImage,
the default path of images and ecc files under AppImage, and a couple
other minor fixes.

We also now get Continuous Build binaries for all supported OSes when
a PR is merged to the main branch, and a Dev series of binaries in a
draft release when the dev branch is updated.
