Workbench: Material specific settings for the specular

- Uses the roughness setting of the basic eevee material
- renamed gloss_mir to roughness
- set default of roughness to 0.25
- renamed ray_mirror to metallic
- cleaned up material rna (BI mirror struct)
- use BLINN phong model
- normalize incoming/outgoing specular light
- when using camera oriented studiolight, the SolidLight will be used
for specular highlights
- EXPERIMENT: when in world oriented studiolight only the shadow direction will be used.
- change the settings of the internal light to make scenes more
readable
