Custom balance alert notifications

[Lonnie Abelbeck <lists@lonnie.abelbeck.com>]

New Feature request,  (Followup to "Tarsnap died" thread)

Consider adding a "Balance Alert" tab

Accounts -> Manage account -> Balance Alert

-=-=-=-

Balance Alert notifications sent to "user@domain.tld":

o- Only when balance is low or negative (default)

o  Additional balance notifications once per year

o  Additional balance notifications once per month

-=-=-=-

Notes:

1. The definition of "year" and "month" could be based on account creation date as t=0.

2. A { Test Alert Now } button, or "Send balance notification within 24 hours" checkbox, would also be useful.

3. Big-tech email systems are constantly adding requirements for email to land in the inbox, (ex: require SPF and DKIM headers).  So being able to know if Tarsnap alert emails are being received would be useful.
