Rekhu updates without a pause, and a picture is fixed in one call

Rekhu is updated often. From now on, you will not notice when it is.

Updates without a pause

• No gap. A new version of the platform starts and is ready before the old one stops. Calls keep being answered during an update; before, there was about a minute in which they were not.
• Work in progress finishes. A version that is being replaced first finishes the calls it is answering, also a long fix of a large file, and the work it started in the background, such as the safety check of an upload.
• Scheduled work runs once. Schedules, the SEO manager's rounds, backups and the nightly work run on one place at a time, also while two versions run side by side, and a job that runs once a day runs once a day, however often Rekhu is updated.

Seshat 1.7.1

• A picture, fixed in one call. A picture sent with any fix, such as add_bleed or convert_cmyk, is made a print PDF at the ordered size first. Before, the call failed unless picture_to_pdf was asked for as well.

Nothing changes in your code.
