Sails 0.12 obviously not compatible with Winston 3.0

**Sails version**: 0.12.13
**Node version**: 6.10.2
**NPM version**: 3.10.10
**DB adapter name**: N/A
**DB adapter version**: N/A
**Operating system**: Ubuntu 16.04

I'm unable to run Sails along with Winston. Looks that Sails is executing a sort of binding.

**The main error is:**
`Uncaught TypeError: this.write is not a function`

**I found a workaround doing the following:**

```javascript
let winstonLogger = createLogger(loggerSettings);
let logger = {
'info': function () {
winstonLogger.info(...arguments);
},
'debug': function () {
winstonLogger.debug(...arguments);
},
'error': function () {
winstonLogger.error(...arguments);
},
'warn': function () {
winstonLogger.warn(...arguments);
},
'log': function () {
winstonLogger.log(...arguments);
}
};
// End of workaround

module.exports.log = {
custom: logger,
inspect: false
};
```

Start by reproducing the reported failure with Sails 0.12.13, Node 6.10.2, and Winston 3.0, using the `this.write is not a function` error as the initial trace. No source file or test is named; done would mean Sails runs with Winston without that error while preserving the reported logging methods.
