Initial integration of providers via API:
- Generic views and modifiers for provider/server selection
- Add in OpenVPNView
- Prepare in WireGuardView
Also:
- Introduce ProfileProcessor, move IAP processing there
- Move .asModuleView() to ModuleViewModifier for proper animation
- Use .themeModal() rather than .sheet()
Also, fix SwiftUI not refreshing when remote profiles are updated. There
was no objectWillChange nor Published around
ProfileManager.allRemoteProfiles, and ProfileRowView was not treating it
as ObservedObject.
Closes#673
Keep two separate stores to accomplish per-profile sharing:
- Local store, where to push updates manually (save/remove/search)
- Remote iCloud store, where to pull updates from
A profile can be added/removed to/from the iCloud store so that other
devices can push/pull updates to it.
Consequently, updates to the iCloud store will NEVER cause a profile
deletion. Once removed, the profile will stay locally.
