Trigger sending of email receipt during import of contributions

[ken]

In the spirit of http://forum.civicrm.org/index.php/topic,5368.0.html I would like to suggest ...

• Adding a Yes/No column for imports called (perhaps) "Send email receipt"
• If not present, this is assumed to be "No"
• When importing a contribution use the setting of this column to decide whether the send an email receipt
• The receipt is only sent if the import for that contribution succeeds

This would allow us to send a receipt to clients that request that.

Thanks for 3.1!
