Release v0.17.5: 0 Follows no more.

The app now caches your follows and uses them to start up. The worst it can happen is to go back to the Amethyst version after updating your follows (or relays) from another client.

- Fixes issue with overriding follow list to zero

- Fixes Notification Dot for Zaps

- Faster notification updates

- Refactoring the saving of user preferences

- More caching to increase the speed of updating lists across the app

- Potentially fixing Notifications crash on Samsungs
