No lighting rendered

[NeoSpark314]

With the current master and the demo application I get no lighting in the demo scene only black geometry (emissive material also seems not to work, but the panorama seems to be correctly rendered)

@NeoSpark314 Stereo rendering is being tracked by issue #32, so can you update this bug's title accordingly.

Regarding stereo rendering, I've found the cause of the issue and am resolving it in commit 39090df, but that unveiled another clipping issue that I'm looking into (i.e: objects don't render unless close to the headset).

I did some further testing. It seems to be an issue with export and with the GLES2 renderer. Exporting with GLES3 looks fine from a lighting perspective. Also it is probably not related to the oculus mobile plugin. When exporting for linux x86_64 the GLES2 render version also renders black (but it works fine in the editor).

Ok; seems to be an actual issue inside the current master: godotengine/godot#31019

This issue was fixed by godotengine/godot#31062 in godot master.
