Migrate operations account to New Alliance

[chadwhitacre]

It seems that we should keep open a bank account for operations for as long as Gratipay, LLC is alive, and it looks like between #1220 and #1205 Gratipay, LLC is going to be alive at least through the end of 2018, and possibly into 2019 or even 2020.

PNC is charging us $12/mo for the privilege of keeping our money there, since we're below the $1,500 threshold for the account. We can get an account with no fee at New Alliance, where we already have our escrow account.

Done. Final PNC payment is in logs repo.
