Update rs-csv-importer.php

[Rebenton]

With the proposed changes here to RS_CSV_Importer::dispatch() merged into master, you could then use the technique seen in this Gist to extend header(), footer(), greet(), and import() in the same way.

I think this is too much extensibility for my plugin. Could you show me an example to use this?

It'll be a couple days before I have it coded, but I need to modify the import() function to iterate through a directory of CSV files, and pass each one off to process_posts(). The greet, header, and footer additions were simply an effort to make the change applicable to a wider audience.

I can update the pull request in about a week or so when I have the "loop through a directory of CSV files" extension coded.

Actually, I think I did mistake to add this function (replace importer class), because it is too complicated.
