graphics/entangle: the port had been updated to transient version (+)
- Belatedly update Entangle to version 1.0 (newer versions are available, but they cannot be easily ported without making changes to the code as they crash with segmentation fault unmodified)
- Now builds itself using Meson instead of GNU autotools and make, hence drop no longer relevant knobs from the Makefile
- Adjust dependencies: remove unused ones, limit the scope of gettext' to NLS case only, drop version specification from USES=python' which is not needed since r564032 and was probably not very accurate anyway
- Reclaim maintainership after previous maintainer had stepped down, and chase HTTP 302 redirection in the MASTER_SITES and WWW line while here
