v1.6.2

Hotfix for the report workflow

LedgerTB v1.6.2 fixes four problems found in review of the v1.6.0 and v1.6.1
report workflow, and completes the Windows shutdown fix. It does not change
book data or require a database migration.

Report and workflow fixes

• After drilling into a report, choosing a different client in the sidebar
  now works. Previously the report link's client kept reapplying itself, so
  the selection silently snapped back. Switching clients also clears the old
  report route from the address, so a refresh cannot bring the previous
  client back.
• Report links no longer pass LedgerTB's temporary window launch code to
  your web browser. That code is what stops other software on your computer
  from talking to the open LedgerTB window. It is not your passphrase and
  not your book's encryption key, and no book data was exposed, but it does
  not belong in your browser's history. The "open in a new tab" control is
  removed, links inside the app now always stay inside the LedgerTB window,
  and buttons that lead to the LedgerTB website or GitHub open your normal
  browser directly.
• Posting a reversal no longer shows an error message after the reversal
  succeeds, and the confirmation checkbox resets so a second reversal is a
  deliberate act.
• The date-format preference screen now always shows the setting of the book
  you have open. Previously, after switching books, it could display and
  save the previous book's format.

Windows

• Closing the window now shuts the app down cleanly, and the installer can
  identify any still-running LedgerTB process before replacing files. The
  first upgrade from an older build can still require ending a leftover
  process once.

Downloads

• Windows: use LedgerTB-windows-x64-setup.exe for the normal
  installation.
• Mac: download LedgerTB-mac.zip, unzip it, and drag LedgerTB to
  Applications. The app is signed and notarized by Apple.
