display out-of-band giving options

[chadwhitacre]

Reticketed from #1896 and #5. We now offer our users the ability to connect a Venmo account and to specify a bitcoin receiving address. We should offer these (and any other related services we add, such as PayPal) as out-of-band ways to pay the user. This is a step on the way to first-class support for one-time payments within Gittip itself.

I've set this as two stars.

So, on the Venmo side - we're working on a payment popup, similar to the "Tweet" popup that Twitter offers, but it's going to be at least a week or two before it's released in production. It should be super easy to use once it's out (I hacked together a version for our demo day that worked fine).

As for Bitcoin, I wonder what the actual "action" that a pay with Bitcoin link would have? Would it just show the receiving address and leave it to the tipper to make the payment?

@thomasboyt Re: bitcoin: yes, though it'd be nice to make clear somehow that attaching a bitcoin address, like attaching a Venmo account, does not actually make it available for adding/withdrawing funds to Gittip as w/ a cc/bank account. The connect accounts UI is a clustermonkey right now. Until ever we get around to cleaning that up, I'd be fine with a Venmo payment popup button near as part of the Venmo listing under connected accounts.

Done at some point.
