RLS: patsy 0.5.0

[jreback]

pandas is removing this deprecation of dtype instrospection functions that were originally defined in pandas.core.common, these are now in pandas.api.types. It seems that the code to fix this is already in master (of patsy), just needs a release to push out. last release was late 2015.

xref pandas-dev/pandas#13147, this will be removed in 0.23.0 (next month or 2).
