Hashrefinery missing from earnings tracker
Hashrefinery (all 3 versions) missing from poolapiref.json, so it doesn't get tracked.

API is the same as most other pools, should look something like:

```
  {
        "Name":  "hashrefinery",
        "EarnTrackSupport":  "yes",
        "PoolUri":  "https://pool.hashrefinery.com",
        "WalletUri":  "https://pool.hashrefinery.com/api/walletEx?address=",
        "StatusUri":  "https://pool.hashrefinery.com/api/status",
        "CurrenciesUri":  "https://pool.hashrefinery.com/api/currencies",
        "PaymentThreshold":  0.003,
        "Total":  "total",
        "Balance":  "balance"
    },
```
