When manually building Fractal with Flatpak, it creates these folders:
- .flatpak-builder/ -- cache folder for downloads/builds
- fractal/ -- build folder, name recommended by the README
Also add .flatpak files (Flatpak bundles), useful when creating builds you want to share for testing.
Allows us to get rid of build.rs, which was only used to
compile resources. static_resource.rs is now created by
meson, and the meson path is used for include_bytes!.
Previously we were using the env! macro to determine
build-time variables like version, app ID, and locale dir.
Instead of relying on env vars, we can create a configuration
file with meson and import it.
I've simplified the project, removing all the tokio communication stuff
and the ruma-client, calling directly to the Matrix.org API using the
reqwest rust lib.
