- Migrated from https://github.com/Yetangitu/owncloud-apps

- substantial bit rot accrued in 4 years of non-maintenance which made Reader unusable
 - Reader now works reliably on public pages - or at least it _Works For Me™_

 - Refactored a substantial part of the code to comply to the "current" (ha ha) Nextcloud API
 - Dropped Owncloud compatibility for lack of a testing installation
 - Dropped IE (<11) support
 - Dropped compatibility with older (<20) Nextcloud versions
 - Dropped app-specific ajax code, now handled by SettingsController
 - Updated dependencies where applicable
