Profiler: Round sample percentages to a constant number of digits

Browse source 
This constant is currently 3 but can be changed easily or integrated
into a user setting. Note that the results are not ideal because during
pretty-printing we're not using any nice rounding rules, so many
percentage values will actually appear as 0.399999 even though they were
rounded to three digits.
