CComponentsHeader uses now CComponentsIconForm, which is now derived
from CComponentsFrmChain. Some methods should be now simplified and
allow to handle some modifications easier.
Use strictly CComponentsForm as parent parameter in constructors.
Some parts have been cleaned up (Constructors, init methodes removed)
New parameter makes it possible already add current item in constructor.
So in mostly situations is it not necessary to use explicit addCCItem(),
but addCCItem()is still valid and necessary in certain situations.
Affected are all cc-classes and their derivates.
Some classes must or can be adapted later. The function is
not currently restricted, because usage of parent parameter is not explicit
defined in constructors, see CImageInfo, here yet are used addCCItem()
methodes.
Generally this parameter is located in the constructors before bool has_shadow,
but it is not sure whether it would be better to use this parameter as the first.
That remains to be clarified.
Member initVarHeader() now used with parameters, so it's possible
to remove multiple code in constructors, but some class must be
renamed to CComponentsHeaderLocalized.
