Subject: Working viewer except for media plugins for now

JSON instead of YAML because there was some warning/error when
I tried the YAML version.
Network sharing needed as a build argument for fetching prebuilt
packages.
I added a device=input finish argument to anticipate devices like
the SpaceNavigator.
flatpak-builder seems to build debug versions of the binaries by
default and install them to lib/debug, and since libraries are all
installed to lib64, the whole lib folder can be safely cleaned up.
The USE_FLATPAK boolean CMake variable got introduced in the viewer
codebase.
The source type is "dir" for now to ease early development, just
drop the JSON file in the viewer source code root directory, and
run as in the build instruction.
Later we should change this to archive or git, so this repo can
stand alone and be ready to be contributed to flathub.
