onIOPort needs to have a ConcreteCPU argument as well; detectCPU() added

Browse Source 
detectCPU() allows us to easily retrieve the current Fail-CPU object which is a regular use case in the aspect headers, now. (Another solution would be a slice in the Bochs CPU class which inserts a reference to the Fail CPU object. Maybe we 'll implement this at a later point.)
