Adds an olive green version based on request. Now you can get a brown, and an olive green.

I have attempted to fix the problem with the olive green backpack not showing up. It was something I probably shouldn't have missed. Anyway here it is.

Strapless, and 25lb/50lb. To install the optional file of your choice, Either take the chosen esp and drop it into your data folder, or take the entire "Meshes" folder from this archive and drop it in the data folder for the strapless version. Overwrite.
