CurrentRecordIndex Does not Update if SkipEmptyLines is True and a row is empty

[gavdraper]

For example

If you have a CSV file with 10 lines and lines 3 and 4 are empty with SkipeEmptyLines == true when it reads record 5 it will have an index of 3.

I'm trying to write logic to ignore the last X records using RowCount-CurrentRecordIndex to determine this but it falls down when the counter is not incremented for blank rows.

I'm happy to look at a pull request if this is change you would accept into CsvReader?
