Added support for rotating normal maps

- Added Normal Map Angle parameter to support rotating normal maps.
- Added light max id parameter to keep shader iterations in the WebGL2 variant as minimal as possible, giving minor performance improvements if not utilizing all 32 lights.

These features shift all parameter IDs by 2, as such existing projects need to be adjusted.
Updated example project to support 1.9.

 - Up to 32 simultaneous RGB light sources per normal map.
 - Linear, quadratic or mixed light falloff.
 - Distance clamping for spot light effects.
+- Supports rotated normal maps.
 - Global ambient light (RGB).
