cgame: load IQM human model

[illwieckz]

Load IQM human model.

Requires:

• models: deduplicate and convert human model to IQM, name it human_male UnvanquishedAssets/res-players_src.dpkdir#19

This should go into a for-x.y.z branch so that developers can keep working on master without having to acquire new assets.

Is there supposed to be any user-visible change from this?

Yes, I'll change the target later. I wanted to push the branch early so @DolceTriade can put his hands on it and have everything wired up to test any new animation he may implement for the psaw or other weapons (flamer…).

Is there supposed to be any user-visible change from this?

No. Any visible change should be considered a bug before being investigated.

The purpose of those branch is only to convert the file formats and file layout to the asset pipeline we currently have the best support for.

One can also see the benefit of using recommended conventions so we can rely on default loaders, meaning we can drop the custom loading implementation.

Migrating the file for the sake of conventions is something I wanted to do for years but the purity win was not worth the effort. Now that @DolceTriade is working on models, making the files compatible with a better workflow and a working production pipeline is worth the effort.

Lgtm but this should be the last thing we merge since it requires different assets
