make account type searchable

[hackmod]

• fixed tools/richlist.js bug with a geth/parity style genesis.json
• support partial accounts update with a given json file. (e.g) $ node tools/richlist.js myaccounts.json

support searchable account like as Account or Contract

or we can use user-defined account type like as follow.

        "genesisAddress": "predefined-addr.json",
        "accountTypes": {
            "1": "Exchanges", // saved as  (1<<3) | 0x4 (user-defined bit)
            "2": "Genesis Alloc" // saved as (2<<3) | 0x4
        },

user defined accounts could be inserted like as follow.

// predefined-addr.json
//...
  "0xfb8b7efb0xxxxxxxxxxxc0f0abc8c555684653587": {
    "type": 20 // 20 == (2 << 3) | 0x4
  },
  "0xfdbdaecxxxxxxxxxxxxxx18d94e0b8533f2801818": {
    "type": 20
  },
//...

I don't think it is a good idea to define accounts and tokens on json, you should rather

1. implement them directly on db
2. force users to customize their accounts
