gsrand v5

• Default content and map lists were updated for Sven Co-op 5.0.
• Fixed multiple crashes with texture randomizing (one of them was there since v2!).
• Program expects to run in the "svencoop_addon" folder and will complain if you put it in "svencoop".
• Sentence randomization (for talking NPCs) is on by default, thanks to 5.0 having 8192 precache slots.
• Barnacles are flipped if they get custom models. Now you can actually see them.
• Increased minimum movement/rotation speeds for entity randomization.
• Disabled the super dense fog. It was just annoying.
• Fixed some display errors when finding content.
• Fixed .res generation and "Copy to folder" not working if "Hide extensions for known file types" was enabled in Windows.
