Subject: [PATCH] bring back client hook that breaks illume2 + contact

i know it's not that pretty, but this brings back the
E_CLIENT_HOOK_CANVAS_LAYOUT as there just is no viable replacement and
thus breaks 2 modules. this fixes T1402 - we chances are just that
this needs a separate hook point as it isnt a per-client but a
per-comp hook.
