re-organize balance information in cosmos accounts API

[ackratos]

asked by @xzjcool . The motivation of this change is response from cosmos accounts API is hard to process (it doesn't consider lock and freeze token). /balances API only return balance information but no sequence number, account number stuff. Frontend developer has to interact with 2 APIs.

We need re-organize balance information (free, locked, frozen) returned by /accounts API:

{  
   type:"bnbchain/Account",
   value:{  
      base:{  
         address:"cosmosaccaddr1hy2e872rqtd675sn72ny87cyyaaanmqeuvwrpc",
         coins:[  
            {  
               denom:"BNB",
               amount:"18394110677945000"
            },
            {  
               denom:"NNB",
               amount:"1793247661328058"
            },
            {  
               denom:"ZCB",
               amount:"1911910581967676"
            }
         ],
         public_key:{  
            type:"tendermint/PubKeySecp256k1",
            value:"A58TeSbC3MRQ1ig5heN/XPinu9kjZrK4gp60DD7czU8J"
         },
         account_number:"0",
         sequence:"227155"
      },
      name:"node2",
      frozen:null,
      locked:[  
         {  
            denom:"NNB",
            amount:"30262100000000"
         },
         {  
            denom:"ZCB",
            amount:"12610100000000"
         }
      ]
   }
}

INTO:

balances:[  
   {  
      symbol:"BNB",
      free:"183834168.27545000",
      locked:"0.00000000",
      frozen:"0.00000000"
   },
   {  
      symbol:"NNB",
      free:"17945178.61328058",
      locked:"302837.00000000",
      frozen:"0.00000000"
   },
   {  
      symbol:"ZCB",
      free:"19125212.81967676",
      locked:"125933.00000000",
      frozen:"0.00000000"
   }
]

While keep the other fields (public-key, account_number, sequence, name)

@ackratos @xzjcool you are right that that the balances API does return free, frozen and locked. Please see #194 for the adjustment to the accounts API to include these fields.
