CComponents: rework position handling

Browse Source 
The real position already used here, if item is bound to a parent.
(bound or embedded means: added with addCCItem() to a form)
This causes no separate calculation in paint methodes of embedded
sub items or sub forms and more nested sub forms.

CComponentsForm have also some new members
- exchangeCCItem() to exchange the order items
- setAppendOffset() to set an offset for auto append mode
 Autoappend is enabled if x or y have value -1 (defined also in CC_APPEND)
 x=horizontal, y=vertical
 Is this activated, no separate calculation of incremental offset
 is required.

However items with independent rendered parts, needs
a separate calculation. In some subclasses was this necessary.
