Sort chapters by upload date (#3180)

* Added sorting by upload date

Spanish 'strings' contains the proper translation for the new feature.

* Added missing sorting cases handling

Previous commit missed some cases resulting in errors at runtime

* Implemented review changes

Shorter UI text and >= date comparison instead of >
