Ideas for revamping Reddit Refresh

Database

Store all previous results in the database, which provides these benefits:
- Can find the most recent by simply sorting by insertion date
- Allows us to display history of results on web interface in case a notification gets deleted
Tables
- Users
  - JWT Token
  - Email (or username)
  - Hashed Password
  - Refresh time
  - Any notifier specific configuration options
- Searches
  - ID
  - Username
  - Subreddit
  - Search term
- Results
  - Time inserted
  - Search ID
  - Title

Notifiers

Instead of being totally tied to Pushbullet, or Gotify, or any other notification service, make a Notifier trait which simply implements a function to send a notification. This could write the notification to a file, or use a service, or write to stdout.
Using dyn Notifier, we can pass these around and store them in our global state.

Handling Changes

Instead of using a REST API, using GraphQL might make it easier to update searches.
- Additionally, if we display previous results, subscriptions will make this easier to do.

Authentication

Since we're not relying on Pushbullet, we'll have to figure out how to do authentication without that OAuth.
- JWT tokens will probably be the easiest for our needs

Display of searches and results

Show subreddit and some searches on card, and then in Dialog show searches, as well as a dropdown for results
