Main changes:

• Switched app signing to apple-codesign-quick (the same signer iLoader uses)
  • Signing is about 6-9x faster
  • SideInstaller is about 5 MB smaller
• Popups that appear together are now merged into one card
  • The pairing code and its Settings steps are now one popup
  • An error and its fix steps are now one popup
  • The "Installed" message, the trust step and LiveContainer's certificate import are now one "Success: last steps" popup
• Added clear explanations and steps for more errors
  • Apple Accounts that are too young to use developer services (error 1102)
  • Running out of App IDs for the week (error 9120)
  • Already having 3 apps installed with a free Apple ID
• Logging in now automatically retries when Apple temporarily rate limits it (HTTP 429)
• Added PanicAnalyzer to the apps that can receive the pairing file

Fixes:

• Fixed LiveContainer + SideStore not downloading while the official LiveContainer GitHub is down (it now uses a temporary mirror, which only has the nightly build)
• Fixed imported .ipa files with spaces, symbols or non-Latin letters in their name failing to sign (error 35)
• Fixed some imported .ipa files that still had parts of an old signature failing to install
• Fixed Side by Side: when two people pair the same iPhone, the second one no longer breaks the first one's pairing
• Fixed not being able to revoke "Apple Development" certificates (the ones Xcode makes) in the Certificates tool (error 7252)
• Fixed AutoFill filling in the email and password separately on the login page
