Update PhotoSwipe to the 2019 release level

[Fraenkiman]

This upgrades PhotoSwipe to the January 8, 2019 release level and is the last version before rewriting to ES6. Fixed the following:

• Fixes an issue with devices that have multiple input types and PhotoSwipe does not wipe.
• Fixes an issue where the layout does not update after an alignment change in some cases.
• Previous FlatPress-specific fixes have been considered and incorporated.
