subtract and division bug

[AStupidBear]

x = [1, 2, 3]
df = DataFrame(Dict(:x => x))
1 - df["x"] 
1 / df["x"]

julia> 1 - df["x"]
0    0
1    1
2    2
Name: x, dtype: int64

julia> 1 / df["x"]
0    1.0
1    2.0
2    3.0
Name: x, dtype: float64

I can't reproduce this on master. I'm seeing correct results:

Of course, that's fixed by #30

Ah, of course. Thanks again for helping out.
