Fix newlines
Merge pull request #647 from cpcloud/fix-newlines-csv-windows

Fix newlines on windows for CSV
PyTables is only with dates
Use reader for into(DataFrame, CSV)
Mongo should consider non option datetypes as well
CSV.reader should infer datetimes and also should not make int64 option types by default
Test that we do not make option types out of ints by default
Add reader vs into test
