Only one pointlight at a time possible

Links to #1140 #1429, reposting because these issues don’t have the error posted and don’t get the attention they really need.

Description When using more than one pointlamp this error occurs: When using Deferred rendering:

This makes it impossible to build bigger scenes in Armory.

When using Sun light source with other sources - no errors. In this case, errors occur even if the light sources are in different scenes of the same project.

Then the problem is happening in Windows Krom export, as it occurs in Krom and Kromx (not tested in C). I will test other builds here and see what happens
