[imp] Mark as unseen in smartmobile

[Ico Izquierdo]

Hello,
I wrote a comentary in ticket [#11677] "IMP mobile view does not provide 
functionality for marking emails as unseen".
I think it would be a good thing if user can read and later mark as 
unseen messages from smartmobile devices.
There are many people that use doing this practice, in order to reread 
later the message and work on it from their computer.

Maybe it's allready posible, but I can't find the option.
