battle and campaign lighting was too dark, tweaked to be brighter

Fixed mod overwriting user graphics preferences, thus being too demanding as it was forcing graphic options.

Fixed calm weather flickering

Fixed crashes. Sorry about that

Added vegetations, trees and rocks from RIS

Added new photorealistic textures
- terrain
- landscape rocks

Added a handful new skies for variation.

Changed campaign and battle lighting

Tweaked Luts for better coloring

Torches appear at specific hours (a bit sooner) to prevent sunset/sunrise battles being too dark overall

Deleted unused files
