Secutor Alpha 5 - Ground and lights remade file

This update adds graphic details regarding general lighting and ground textures. The 4 light presets are dawn, midday, dusk, and night. The shadows, strength and general tone of the main light are randomized. Additionally, fog may occur.

Regarding the ground, several textures have been added. They are linked to the environment. Regions with high humidity contain more green and dry regions are rather sandy. There is a nice gradual change to each region. The grass / flower area appears to be a bit crowded to the eye, this will be fixed in the future.

The next update will focus on sound.
