Make selecting of expanded layer items a bit nicer

Now only selects when clicking on item header, nothing happens if you click in the expanded area. Also fixed a bug where selecting expanded items wasn't working.

Correction to 2ca18d608cd5dc

Fix last layer item sometimes not drawing selection

Layer boxes to fill empty background was drawing over it.

Support for expanding layer settings

A selected layer now shows a gear wheel icon which expands the layer settings. The layer settings are currently two dummy text buttons.

Added parameters IOR and Transparency for refractions

With this, the Disney BRDF/BSSRDF is extended by the BTDF part.

Removed the unused "simple" (without derivatives) compiler implementation.

As long as the compiler class is WIP the two implementations go out of sync too
easily. Better to make a copy of the dual version and then reduce it when the
compiler class is reasonably stable.

Removed the WITH_IRMODULES option, used previously for loading IR code from text files.

This approach suffers from difficulty of generating machine-independent IR code
and is better generated using the C++ API directly. The llc tool can be used to suggest
implementations with C++ API usage, see for example
