UPBGE: Cleanup UI.

[panzergame]

Some unused options/entities are removed from the UI in game engine mode:

• scene keying set
• scene audio
• speaker and forec filed in add menu

Also the game engine is renamed UPBGE.

Fix issue #756.

[UnidayStudio]

I agree with the changes. But I'd like to point again that instead of removing the sound speaker, it's a good point to make them actually works. This is a redundant design decision (since we can archieve the same result by simple adding a logic to a normal object). And there are seveal different opinions about redundancy in design, but this is a good point:

"A Designed Redundancy can be a powerful mechanism to enhance the speed, discoverability, and learnability of your products. In some cases ... ... they can be a core component of how your product delivers an experience."

I'd like to point that a speaker is much more intuitive to the new user to be a "sound reproducer".It will increase the discoverabilty of these feature (sound) in the engine. And, of couse, even for the experienced user, having a GameObject that is alrady prepared to reproduce sounds, without any other configuration, will increase the development speed.

That's an issue on its own that deserves its own PR. Better remove the item from the UI until it has an actual purpose.

I agree with this patch and I agree both with @UnidayStudio and @marechal-p remarks

We can remove Area lights as well

[panzergame]

I can't remove AREA in the lamp type enum because the front end UI doesn't provide a way to filter enum properties.
Otherwise it possible to replace the UI of area lamp by a message like 'not supported in game engine'.

@lordloki : The function using these variables is:

void BKE_sound_update_scene_listener(struct Scene *scene)
{
	AUD_Sequence_setSpeedOfSound(scene->sound_scene, scene->audio.speed_of_sound);
	AUD_Sequence_setDopplerFactor(scene->sound_scene, scene->audio.doppler_factor);
	AUD_Sequence_setDistanceModel(scene->sound_scene, scene->audio.distance_model);
}

Though it is using scene->sound_scene which doesn't seem global or registered to a global variable and also not used by the game engine. The type of AUD_Sound is also strange.

I didn't do a deep research, @lordloki : Do you have a example of these values used in game ?

[lordloki]

@panzergame : In void LA_Launcher::InitEngine() you also have:

#ifdef WITH_AUDASPACE
	// Initialize 3D Audio Settings.
	AUD_Device *device = BKE_sound_get_device();
	AUD_Device_setSpeedOfSound(device, m_startScene->audio.speed_of_sound);
	AUD_Device_setDopplerFactor(device, m_startScene->audio.doppler_factor);
	AUD_Device_setDistanceModel(device, AUD_DistanceModel(m_startScene->audio.distance_model));
#endif  // WITH_AUDASPACE

@lordloki : These attributes are now exposed.

@panzergame I have a issue with audio panel when revert to other render from UPBGE.

Fix plus cosmetic refactor: https://gist.github.com/lordloki/a34ef600e1255f4b93d087eaaf7505e9

The audio panel is now:

Good work.
