refactor creation of default parameters

Currently the creation of the default parameters is hard-wired in ICA.createDefaultParameters(). We had now 3 issues on the list, where another Parameter-Implementation instead of ComponentParameter would have been better:

Configuration aware (Julian Stern's problem):

• http://lists.codehaus.org/pipermail/picocontainer-dev/2004-April/003406.html
  Thomas Heller's AutoConfigParameter:
• http://lists.codehaus.org/pipermail/picocontainer-dev/2004-April/003407.html
  Thomas Heller's problem with the Pico autoregistration:
• http://lists.codehaus.org/pipermail/picocontainer-dev/2004-April/003295.html

We might either move createDefaultParameter to (Mutable)PicoContainer or to create a container that overwrites the fucntion or have an additional ctor arg for ICA:

class ICA {
public ICA(Object componentKey, Class componentImplementation, Parameter[] parameters, ParameterFactory factory)

public ICA(Object componentKey, Class componentImplementation, Parameter[] parameters)

}

class ParameterFactory() {
Parameter getDefaultParaeterForType(Class type);
}
