Changed ambient handling for Phong and Lambert materials.

Removed diffuse color influence on ambient term in Phong. This was causing texture disappearance when diffuse color was black.

Made Lambert more similar to Phong: now it also has ambient color parameter. Before ambient light was affecting Lambert as if ambient color was always 0xffffff.
