DataFrame.rolling.apply does not appear to support kwargs
#### Code Sample, a copy-pastable example if possible

``` python
import pandas as pd
import numpy as np

def subtract_custom_value(x, custom_value, debug=False):
    return x-custom_value

# this works (no rolling)
series = pd.Series([20, 21, 12])
series.apply(subtract_custom_value, args=(5,), debug=True)

# this complains "TypeError: apply() got an unexpected keyword argument 'debug'"
rows, cols = 20, 1
df = pd.DataFrame(np.random.randint(0, rows, size=(rows, cols)), columns=map(str,range(cols)))
df.rolling(10).apply(subtract_custom_value, args=(5,), debug=True)
```
#### Expected Output

Would expect the rolling case to be the same as non-rolling.
#### output of `pd.show_versions()`

```
