• bounty3 is most minimal bounty, without any dependence on the other modules
• client and cli boilerplate are complete

I'm storing them locally for now and will rewrite them later...There are some edge cases which are explored in bounty, bounty2 and grant i.e.

• group governance of bounty to (1) vote on every decision among the group (2) allow challenges to dispatch votes on only challenged decisions
• revoking contributions

Neither of these are covered in the current version because they add more complexity than they're worth.

We should at some point add something for closing a bounty, but returning funds to contributors is hard if any spends have been made. There is no explicit dilution mechanism for contributors and that ambiguity makes things a bit more complicated. I have some ideas here, like, for example, forming an OrgId from the Vec<(AccountId, Balance)> which comprises the state of the BountyTips map and then make_prop_donation to that OrgId with the remaining funds. This would ensure that the funds received are proportional to the tacit ownership in the bounty implied by existing contributions.
