On macOS the Adwaita icon theme is not installed by default, so
symbolic icons (edit-copy, auth-fingerprint, network-wired,
dialog-warning, etc.) render as the "image-missing" placeholder.
Bundle the symbolic SVGs used by the GTK frontend into the embedded
gresource so the app is self-contained and doesn't depend on any
system-installed icon theme. The existing
`IconTheme::add_resource_path("/de/feschber/LanMouse/icons")` call
already tells GTK to search this prefix, so no code changes are
needed.
Icons are sourced from Adwaita and placed under the standard
`scalable/{actions,devices,places,status}/` hicolor layout.

*breaking change*
this changes the configuration syntax, allowing for an unlimited amount of configured clients.
Also a first step towards enabling a "save config" feature.
client configuration now applies immediately instead of after enabling / disabling clients.
Also fixes a potential feedback loop when changing settings.
