"Mined" to "Minted" for StakeMint transactions

I am a noob so this could be completely wrong but as noted in this reddit thread it makes more sense to say "Minted": http://www.reddit.com/r/MintCoin/comments/22818m/mint_wallet_mining_by_itself_wtf_is_going_on/
Update README.md

Fixed markup and added PoW removal info
Add "Minted" Translation to bitcoin_en.ts
