[imp] Imp 3.1 (final) bug with session expiring - fixed

Me a moment ago:

I supposed wrong. When a session expires, clicking on an imp function (INBOX, 
Compose etc.) the following login fails, but clicking turba or kronolith icon, 
login is fine. In turba and kronolith the logins following an expired session 
are fine.

It would seem that Imp is missing an urlencode() function which is present in 
Turba and Kronolith. e.g. in mailbox.php, there's

header('Location: ' . Horde::applicationUrl(IMP::logoutUrl('login.php?url=' . 
Horde::selfUrl(), $reason), true));

while

header('Location: ' . Horde::applicationUrl(IMP::logoutUrl('login.php?url=' 
. urlencode(Horde::selfUrl()), $reason), true));

works.
