Updated Abilities.js

The  abilities script is updated, now Pistols will change the page. On
the pistols page if the top button is clicked the current levels will be
change to what the previous next levels said and the next levels will
increase as well. Right now the numbers are set directly because i could
not get the script to pull nicely when i tried the following in the case
statements damage = nextDamage; it kept changing the following number.
If you change the variables under the case statement for the
CurrentAttributes to say the above statement then you will see the error
i was having. any suggestions feel free.
