New Atavism Features part 1

We are doing some nice progress with the new Atavism Editor and polishing it for both Unity and Unreal users. We added logs with a rotator for easier troubleshooting. We also added handling of more image formats like TGA and BMP for items, crafting recipes, abilities, effects, skills, currencies, and building objects icons. As a side note, we are working on the new features for the Unity version that we will also want to port to the Unreal like stealth mode, shields, sprint, trigger effects, that can react based on events Dodge, Miss, Damage, Heal, Critical, Kill, Parry, Sleep, Stun with a chance to trigger ability or effect, based on the dealt or received ability/effect with defined tag.
