Clean up ColorationKS

canExecute/Timing:

• in principle, it is not very sensible to set the BlockSize of the binaural simulator to a higher value than what is used as timestep in AuditoryFrontEndKS. What is your motivation to set the Blocksize that high?
• You still can do the same thing with maxInvocationFrequency: set it to (SampleRate/BlockSize).

Concluding: I still vote for getting rid of this code/functionality duplication, which is always a bad thing ;). OR we discuss how to adapt the existing functionality to your needs.
