Add more altcoins

Merge with https://github.com/daniel-lima/bitkey for dash, monero, and ripple.

[estevaocm]

The bip39 wallet introduced in v1.03 makes this merge redundant. Only Monero is missing.

[estevaocm]

Most relevant currencies to add: Iota, Monero, Raiblocks.

Might be a good idea to include an offline wallet for signing XRP transactions as well. Maybe https://github.com/jatchili/minimalist-ripple-client?

Considering relevance due to market caps (https://coinmarketcap.com), priorities should be Cardano/ADA, Dash (cold wallet if possible, otherwise use Exodus), NEM/XEM, Bitcoin Gold/BTG and Monero/XMR. Verge/XVG has also been cited as relevant.

[estevaocm]

Jaxx could also be included to expand currency options in hot-online mode, e.g. Augur and ZCash.
