[Lazarus] TComboBoxEx and TCheckComboBox

[Vojtěch Čihák]

Hi,
 
I implemented TComboBoxEx and TCheckComboBox.
The first is combo with images. This control is in Delphi7 too. My implementation has one difference - it is readonly, because I needed csOwnerDrawFixed for painting.
The second is combo with checkboxes. Internally it uses Items.Objects[] for storing State and ItemEnabled.
Some known issues are described in README.txt which is attached in archive. 
Package in comboex.zip is now available here: http://bugs.freepascal.org/view.php?id=26515#bugnotes 
 
So it's up to Lazarus managers to decide whether the components will be part of Lazarus or if I should make them in separate package or part of my EC-Controls.
 
I tested them in GTK2/Qt4 and Wine, so some test in Carbon is welcome.
 
Thanks.
