Fixed code that displays the page heading so it displays the correct one.
Removed non-standard code from mysql call.
Added newsletter option along with the code to filter by it.
Added code to enter a start/stop date.
Changed code so the report is not ran until submit is clicked. Automatically running it creates problems with sites with a large number of customers.
Made minor changes to the code for formatting and displaying an error message.

This is a full package.
