Improve display of favorites for ties

[JacobEvelyn]

Currently, we display favorites like so:

1. Marie Curie              (3 activities)
2. George Washington Carver (3)
3. Elizabeth Cady Stanton   (3)
4. Someone Else             (2)

When in reality the top three friends are all tied for first place, so they should be displayed either like this:

1. Marie Curie              (3 activities)
1. George Washington Carver (3)
1. Elizabeth Cady Stanton   (3)
4. Someone Else             (2)

or possibly like this:

*1. Marie Curie              (3 activities)
*1. George Washington Carver (3)
*1. Elizabeth Cady Stanton   (3)
 4. Someone Else             (2)

I think my leaning is for simplicity's sake to not have asterisks or any special indication for the tied numbers.
