add BIP-39 entry for passwords in vault

Browse source 
If the "notes" field starts with the characters
"bip39" (case insensitive), then, the password field is
interpreted as a hexadecimal encoding of BIP39 entropy.

To create a BIP-39 entry, leave the password field blank,
and then start the Notes field with the characters 'bip39',
and this will trigger a dialog box that will only allow
valid bip39 entry and check the checksum etc.

To view the BIP-39, after opening up the entry for "edit",
close it, and it will pop up a second dialog box that interprets
the hex data as BIP-39 words.

You could also in theory enter the hex digits yourself into
the password field, if you're masochist.
