Version 2.1.0: Drop Electron and remove legacy profile migration
A major part of the Firecrypt codebase has been updated to no longer use
Electron. Instead, native webviews are now used. This brings both
performance and user experience benefits. However, it does increase the
difficulty of porting Firecrypt to platforms other than macOS. This
version also drops support for migrating legacy profiles. Attempting to
open a legacy profile will now show an error message. If you have a
legacy profile you need to migrate, use commit 69b87376d4.
