improve handling of competition reward splits that don't sum to 100
Currently we require that a reward split in a competition proposal must add to exactly 100. Perfect precision. It is hard then to have a close split between three winners, has to be 33-33-34. We would like to allow 33-33-33 with leftovers that will flow back to the dao, and even better, higher precision on the proportions to minimize the amount leftover, allowing us to get closer to a sum of 100.
The logic could be this:
When rewardsplit is [n0, n1, n2, ... nx] the individual rewards are n_i / (n0 + n1 + .. +nx)
For example:
rewardsplit [90,10] for first winner 90%, second place 10%
rewardsplit [1,1,1] for getting three equal parts
rweardplit [1,1] is equal to [50,50] -> two equal parts
etc.
