Create a new createLogger module for better debugging. Each logger has its own log level and its own createLogger that will nest logs underneath them. `player.log` is also included, which logs the player id as part of the log statement. The history API also got a filter method.
For example:
```js
var log = videojs.log.createLogger('foo');
log('hello');
// > VIDEOJS: foo: hello
```
