Multi-line header rows

[rufuspollock]

This has come up a few times now - including just now in frictionlessdata/forum#41

I think the easiest would be to change header in csv dialect to be a number. This has advantage that current true and false values convert over to 0/1 quite nicely.

• Support ignoreRows for TabularResource Support ignoreRows for TabularResource #344
• Make the header row in the CSV optional Make the header row in the CSV optional #326

Behavior

Tooling behaviour needs to utilize this.

Research

• csvstack eats rows if files have no headers wireservice/csvkit#188 - csvkit supports --no-header now
• Postgres COPY command as used in Redshift has "ignoreheader" as a number which is number of rows to skip: http://docs.aws.amazon.com/redshift/latest/dg/copy-parameters-data-conversion.html#copy-ignoreheader
