Crowdfunded enqueuing

[gbl08ma]

Similar to what's described on https://www.reddit.com/r/JungleTV/comments/onnut1/crowd_funding/ minus some of the limits. Rate-limiting for enqueuing proposals coming from the same user can be implemented by increasing the down-payment with every successive simultaneous attempt, instead of hard-limiting to one proposal per user. In fact, it would be an interesting idea to make the down-payment amount increase with the number of active proposals, regardless of who made them - this means the number of active proposals can increase indefinitely, but at a cost to those wanting to increase it beyond reasonable points, much like what happens with the queue length factor in the main media queue.

Each active proposal gets a fixed payment address from the pool. Active proposals would need to be stored in the DB as to not lose track of their funds/state/address. The addresses would need to be taken from the pool again on start-up (this represents a change to how the address pool works, since right now it is kind of a "free list" that contains addresses that were once used and are free to use again. We'd need to introduce the concept of taking a specific address from the pool instead of just asking it for an arbitrary one.)
