CLI: fieldcraft-cli crashes [list|show|replay|dir|clear] (#107)

Lists, shows, replays and deletes the crash reports the desktop app
wrote. A replay opens the report's model, runs its commands with writes
confined to a scratch folder, and says whether the same internal error
happens again. Adapted from SolidCraft's solidcraft-cli crashes.
