Squashed commits due to rename:
* meson: Update reaper default_options (doesn't work)
* meson: Generate version information for `ULWGL_VERSIONS.json`
* meson: Use meson string interpolation
* meson: Add man pages to meson
* meson: Use configure_file instead of sed
* meson: Use ulwgl version for reaper too
* meson: Rename ulwgl to umu
