NDC Feature: Leaderboard shows points earned in last 60 days

[SSWnathanmills]

The points that are displayed on the leaderboard are currently calculated separately from the points displayed on a profile and the points already include the date earned. With this functionality already in place, the only thing that is needed is to add a filter to the leaderboard page that will only include points earned in the last 60 days.

As per our discussion @SSWnathanmills @AndreasLengkeek @MattGoldmanSSW @adamcogan

These are the proposed changes to the leaderboard:

• We want to update the leaderboard to be a rolling total
  i.e: time period of 90 days
  (include a time-filter)
• We want to add a new point value to the user. (balance)
  I.e: total points accumulated minus rewards claimed
• The points shown on the leader board are the balance.

Superseded by v2. Leaderboard is now this month, year, or all time.
