[evolution-patches] Do not let message list steal focus

[Jan Holesovsky <kendy suse cz>]

Hi,

When using a mail client, I want to control it only using keyboard.  In
Evolution, the possibilities to move inside the message, and between
messages, include the Up and Down arrows (to move inside the message)
and Ctrl+], Ctrl+[, Ctrl+PgDn, and Ctrl+PgUp (to move between the
messages).

The problem is that any of Ctrl+], Ctrl+[, Ctrl+PgDn, Ctrl+PgUp steals
the focus from the message view, and gives it to message list - in which
case the meaning of Up and Down changes to moving between the messages
which I do not want - that is what Ctrl+PgDn and Ctrl+PgUp is for ;-) -
and you have to press Tab to get to the message view again.

The attached patch removes stealing of the focus - with that, you can
stay in the message preview & browse all your mail quickly and
effectively.

Please consider for inclusion.

Thank you,
Kendy
