Let us config email subject, from- and to-addr per cam

[packetguy]

Currently you can only configure the from- and to-address fields for email notifications, and then there is only one set of value for all cameras. I'd like to use different values for each camera. Also, I'd like the ability to configure a unique subject line for each camera too (e.g., "Video alert from garage cam1"). As it is, I get a ton of emails all from the same email address with identical subject lines, which makes it very hard to sort through which emails I want to take the time to view on my iPhone over a somewhat slow AT&T cellular Internet connection.

I'm a software engineer for both Windows and Mac development;this seems like it should be an easy change.
