[evolution-patches] New patch for composer, remove attatchments with "Delete" key

[Bruce Tao <bruce tao sun com>]

Hi, all

I find there is a bug in the patch provided previously by
*Paolo Borelli * pborelli katamail com <mailto:pborelli%40katamail.com>,
which deals with removing selected attachments by pressing "Delete" key.

see 
http://lists.ximian.com/archives/public/evolution-patches/2004-January/004190.html

That is after removing one of the attachments, the focus will disappear. 
And then
if you press left, up, or down arrow key the program will crash.
This bug can simply be fixed by adding one statement to set focus to the 
first icon,
as I propose, while keeping all the modification by Paolo.


Please review , thanks!
:-)
