Shelve work on #1073
Rough in new team split; #1073

We now have /members/ instead of /split.html. It lists members of the
team in question, and the team participant can add new members. Members
can't change their take yet, but the take, balance, and percentage is
displayed. I'm going to work on the payday side now.
Don't let balance go below zero in display; #1073
Always show total receiving on members list; #1073
Modify pachinko method for kids-eat-first; #1073

This also removes the old compute_split method and split.json endpoint.
There is no computation now, we split on absolute numbers.
