Add option to hide index in pandas.Series.to_string

[ccsv]

In the Dataframes.to_string function there is a option to not print the index:

index : bool, optional

whether to print index (row) labels, default True

Can this be added to the Series function to_string?

sure that could be made consistent, pull-requests accepted.

Though in general this routine is mostly used internally.
