Footpads Recieve a Slight Tone to Nim

Update 10/8/2014:

- Nim has been toned in the following way:

- slightly reduced gold and exp for normal use
- moderately reduced gold and exp per augment

These changes are necessary to balance nim with respect to the changes in power scaling of augments after the pwipe. Further modifications will be made in the near future if they are necessary to bring nim more in line with other abilities.
