Title: Add ability to disable boundary adjustment when replacing markers

Pretty self explanatory and a simple change. Not in all occasions do we need the boundary adjustments happening. I kept this to default to true like the current functionality.

If you want to disable the boundary adjustment when replacing markers, all you have to do is pass false after the markers:

```javascript
Gmaps.map.replaceMarkers(data, false);
```
