Bug in Breast Cancer Wisconsin dataset

[mrektor]

Hi everybody.

I found a small bug when fetching Breast Cancer Wisconsin dataset:
The target class is not the last column but the first one.

This can be solved in code by simply querying for the "target" column, but for consistency I think should be fair to consider moving the target class to the last column.
