[Evolution] Shortcut key for "insert attachment" changed 2.4->2.6

[Ow Mun Heng <Ow Mun Heng wdc com>]

Now, Whose's bright idea (said with glee!) is it that decided to change
the Shortcut key for Evolution's Insert->Attachment from Ctrl-Alt-A to
Ctrl-M?

Why was this changed, btw?

(I also noticed that there's no more usage of the "alt" key in any of
the shortcut keys)
