FR: auto-wait for clouds to disappear

[hannobal]

Feature-request: autowait_clouds = true/false option, which would change autowait (5) behavior so that it will wait for clouds from spells to disappear.
Why? With freezing cloud, player is often blocked by clouds they have created. Then player has to wait with "." turn by turn for clouds to disappear, or waste turns with autowaiting ("5"), if they're at max hp/mp.

Also, autoexplore should know when clouds created by player have timed out outside LOS (if you have created clouds blocking autoexplore path, autoexplore will assume the clouds are still there if they timed out outside LOS).
