Subaddresses

Haruto has sent a PR for subaddresses and we need more testing to make sure it works flawlessly.

https://github.com/sumoprojects/sumokoin/pull/28

You can also pull and build from Haruto's repo branch here:

https://github.com/haruto-tanno/sumokoin/tree/subaddress

You may use testnet for coin transfers or use small sum to avoid lost real money if there is any issue.

This is my test screen, the subaddress (that I sent coins to) starts with Sub... instead Sumo...:
