Some improvements:
- Suggest replacing the template with the description of the issue
- Attach app log
- Append purchased features
Also reuse the same body for `mailto:` reports, as metadata were not
being attached in that case.
Closes#377
As the only link to "Diagnostics" appears in the profile screen, when
there are no profiles the screen is unreachable. Replicate the same
entry in Settings.
Move all persisted state out of AppManager to where it really
belongs. To do that, inject a shared KeyValueStore object into
managers that need to persist part of their state in a strongly
typed manner.
Below are persisted states:
- PersistenceManager
- persistenceAuthor
- ProfileManager
- activeProfileId
- UpgradeManager (formerly AppManager)
- didMigrateToV2 (migrate former value)
- VPNManager
- tunnelLogFormat
- masksPrivateData
A similar approach is used for app-specific preferences, by using
a strongly typed enum (AppPreference) together with SwiftUI
@AppStorage property wrapper.
Worth moving logging logic into a specific LogManager.
Finally, drop any former view dependency on AppManager, as states
are now accessed through specific managers.
