CComponentsHeader: add header buttons to header form

Browse Source 
Use addHeaderButton() to add any button icon ont header form.
The buttons have a right alignment, this means, the first button
is on the right boarder of header.
For existing instances it's recommended to remove old button icons
before add new buttons, otherwise icons will be append.

See also sample code in CTestMenu.
