[geary] Allow from:me/to:me/etc. in search box

[Charles Lindsay <clindsay src gnome org>]

commit 48944449a2bf8ce014e3d43ce49611e3c6efa3f3
Author: Charles Lindsay <chaz yorba org>
Date:   Fri Feb 14 12:53:10 2014 -0800

    Allow from:me/to:me/etc. in search box
    
    This simply replaces the "me" with your email address.  Highlighting
    follows suit.
    
    Closes: bgo #720875
