Framework ignores set order in vkCreatePipelineLayout call

[jdahl]

Seem like the framework ignores that set order is important during the vkCreatePipelineLayout call so that the sets are in the correct order. It adds the sets in the semi random order that exists in descriptor_set_layouts. A fix for this can be to change

std::transform(descriptor_set_layouts.begin(), descriptor_set_layouts.end(), descriptor_set_layout_handles.begin(),
	               [](auto &descriptor_set_layout_it) { return descriptor_set_layout_it.second->get_handle(); });

to something like

	for (int setNr=0; setNr<4; setNr++)
	{
		if (descriptor_set_layouts[setNr] != nullptr)
			descriptor_set_layout_handles[setNr] = descriptor_set_layouts[setNr]->get_handle();
	}

in pipeline_layout.cpp
The change above assumes you use all sets in sequence. If there is holes in the sets like you dont use set 0 the framework should inject a empty set layout.
