Patch to execute a command when getting new mail

[Yoshiki Vazquez Baeza]

Hello,

This patch adds a new setting that you can configure to execute a
command every time new mail is found in your current mailbox.

In OSX I have it set to the following:
set new_command="terminal-notifier -title '%v' -subtitle 'New Mail in %f' 
-message '%n new messages, %u unread.' -activate %'com.apple.Terminal'; afplay 
%'/Applications/Mail.app/Contents/Resources/New Mail.aiff' &"

The first part will format some information about the status of the
mailbox and pass it on to terminal-notifier
(https://github.com/alloy/terminal-notifier) then use OSX's afplay to
play the classic "new mail" sound.

I'm very interested in hearing what other mutters think about this
patch.

PS - Santiago Torres (CCd) and me pair-programmed this.

Thanks!

Yoshiki.
