Provide option to show how often (%) of each number of tricks taken is achieved

[sievers2501]

What we currently have is the average number of tricks, and the standard deviation. That's great. Eventually we will want to see some kind of histogram or textual representation of how often each number of tricks was made. For example, for a 3NT outcomes, we may have an average number of tricks as 9.2, but we would want to see something like the following.

50 results
7 tricks: 1 (2%)
8 tricks: 5 (10%)
9 tricks 31 (62%)
10 tricks: 11 (22%)
11 tricks: 2 (4%)

This would supersede issue #153
