Docs for error_bad_lines, and warn_bad_lines options to pd.read_*
Hi,

Added some docs for error_bad_lines & warn_bad_lines, as currently there aren't any found here: http://pandas.pydata.org/pandas-docs/dev/generated/pandas.io.parsers.read_csv.html

Seems to me the docstring template used for all the methods makes it difficult to track 
which args apply where, but this is good.

merged. Thanks!
