Export and Import Mnemonic (BIP39) #34
Description
This is something we should really implement before releasing. Backing up properly is quite important.
Research to be done (@Zimonzk pls): BIP39 can be somehow used to create encrypted wallets with those mnemonic phrases. If possible we should make those (optional) either with the users default password or with a one time password just for exporting (for extra security). Importing BIP39 wallets with passwords should also be possible.
