v0.6.1

• PDFs attached from Gmail are filed again. Gmail's web client marks every file it attaches
  in a way Harbor read as an inline picture, so a bill forwarded or sent from Gmail was skipped
  without a trace — the water bill that surfaced this was scanned by two installs and filed by
  neither. Mail that arrived before this release was never recorded as seen, so a Scan
  history over the last month from Settings → Mail picks it up now.
• A mailbox that drops out once is retried. A single failed connection marked the mailbox
  unreachable and the five-minute sweep then left it alone for good, until someone pressed Test
  in Settings. The sweep now keeps trying; the Inbox still says the mailbox is not connected
  until a pass succeeds. A rejected password still waits for a new one rather than retrying.
• You choose the currency on a to-do. A to-do typed by hand was always stored in euros,
  whatever you meant, and one proposed from a document carried whichever currency the model
  assumed when the page showed none — so a dollar bill could sit on the list as "€5,792.25".
  Every place an amount is entered or accepted now has a currency beside it (€, $, £, CHF), and
  when a document does not state one the to-do says so with a "?" instead of guessing. Existing
  to-dos keep what they have; correct one from Edit on its document.
• Search results now show the people, things and tags a document is about, and how it arrived,
  as labels under the matched text.
