New way to deal with incomplete dt columns. Leaving the NA's as they come, and adding a date column.

Fixes #140. So now, if a column that is modernly displaying date and time, it still gets returned as a POSIXct dateTime. If some of those columns are only dates, a time of noon...with the median time zone offset...is added, and a new column is created to indicate a TRUE/FALSE date flag.
