Added a readme text file.

Added an "optionals" folder that contains 2 additional pbo's

The pbo's in the "optionals" folder are configured to add a fatigue penalty when the backpack is equipped.

The "eo_zodiac_backpack_jog" pbo limits the player to jog or walk, the player cannot sprint when the backpack is equipped.

The "eo_zodiac_backpack_walk" pbo limits the player to walking only, the player cannot jog or sprint and is instantly fatigued when backpack is equipped.
