[evolution-patches] Resubmit patch for bug 45631, "activate popup menu in mail composer's to/cc"

[Maxx Cao <maxx cao sun com>]

Hi,

Corrections made according to Mike's comments. I can't hook this to "popup_menu" event, 
because e-text is not inherited from GtkWidget.

Please review this new one. Thank you!
