Version 1.31

Version 1.31 is released!

The main new improvement is that photos are now processed in the background, meaning the preview restarts sooner (especially if options such as auto-stabilise of photo stamp is on).

Continuous focus mode now supports touching to autofocus (this also helps if flash is on, now touching to focus in continuous mode will turn the flash on if necessary, as with auto focus mode).

There's a new option for filenames to be based on UTC (Zulu) time (thanks to David Pletcher). The Russian translation is updated (thanks to Grigorii Chirkov). And various other fixes.
