[taskmanager] Add setting to skips iconified tasks using mouse wheel
1e546f4e changed the taskmanager so that iconified tasks inside and outside tasks groups are skipped when using task groups. However, this change wasn't toggleable and enforced on the user.
This patch provides a toggle that can be used to skip iconified tasks. The default for this option is 'True' i.e to skip options. The use has to explicitly disable this behaviour, since users might have already gotten used to the new behaviour.
