Playouse - CSV Loader - should accept file object, or handle files in universal-newline mode
Agreed, good idea.

In file `playhouse/csv_loader.py`

When you use `load_csv`, it expects a filename of the CSV file. If the CSV file has been saved in a slightly different format with respect to New Lines (which is common with csv files generated by MS Excel), the standard `open(filename, 'r')` won't work.  

```
Error: new-line character seen in unquoted field - do you need to open the file in universal-newline mode?
```

The code which opens the provided filename should read `open(filename, 'rU')` or alternatively, you should be able to provide the function a file object.
