More Metrics on Player Details Page

As pointed out by @Jamesargy6 , most traffic on the site is from
- Admins
- TOs
- People obsessed with their rankings

In order to attract the average player to visit more often, more metrics could be added. 
Some ideas include
- W/L Ratio
  - Overall W/L
  - W/L for past PRs
  - W/L for the current PR
- Performance over Time Graph

If any more ideas, comment below!
