Putter sensitivity multiplier

The slightly requested putter sensitivity is here

• Added a putting sensitivity multiplier

I also tweaked max club distances for irons to have a more natural increase in distance from club to club.

• PW -> 120

• 9I -> 130

• 8I -> 140

• 7I -> 150

• 6I -> 160

• 5I -> 170

• 4I -> 180

• 3I -> 190

Last time I touch distances I swear. This range just makes sense.
