Enhancement: add address columns

[philmb]

Thanks for this simple, handy extension. Since we (and probably others) like to send physical cards, it would be great to have the mailing address fields as column options in the report. I played around with the code, but I really don't yet know enough to get it to work.

Additionally, changing line 29 of birthdays.php to:
protected $_customGroupExtends = array( 'Contact' );
allows custom fields like the Summary Fields extension (which includes fields like "most recent contribution" "most recent event attended") to be included. This can add to the personalization of birthday greetings.

Thanks @philmb, I think that's a good idea. I'll look into this when we release the next version.

BTW: are you using 1.1.beta1 or 1.0? Does it work properly?

[philmb]

1.1.beta1 Seems to be working fine.
