Build on top of a previous update sent by Jérôme (Neon King)
which was build of an update sent by Donovan.
Port changes:
- switched to GH_*
- moved to cmake and dropped BAM
- dropped unnecessary patches (all of them)
- avoid git from running (new patch)
- the strict-alignment crash is resolved
- replaced SDL with SDL2
- update to python3
I'm taking maintainer. The maps distfile is hosted by solene@.
With help from: Donovan Watteau (previous maintainer), Jérôme, sthen@,
solene@, and Daniel Dickman
Some crashes and graphic issues have been reported. We decided to import
it anyway because the old version is incompatible with current servers.
OK from thfr@ and solene@
