Add Blank Row in Classification Template Downloads

When downloading a Template from classification importer, it would be nice if a blank row was inserted in line 4, as is expected when you upload back into Adobe.

Something like

##SC Header##

##SC Header Two##

Key     Column1     Column2

Key1   Col1Data1     Col2Data2

Key2   Col1Data2     Col2Data2

It might help new users from having to hunt for the "Troubleshooting classifications" article which mentions the issue 3/4 down the page
