Change default `HISTFILE` path from `~/.zhistory` to more conventional `~/.zsh_history`. This aligns better with Debian variants, macOS and Oh My Zsh. This would provide an easier onboarding experience to users coming to Prezto from standard (framework free) zsh or from Oh My Zsh. For existing Prezto users, we attempt to automatically rename old `HISTFILE` to new one iff the old one exists and the new one doesn't. However, if both old and new `HISTFILE` exist and the old one is more recent, we just alert the user about what changed with a suggested way to accommodate the change.
