Combobox does not honor 'Displaymember'

[David Berglund]

When the ComboBox has its DisplayMember property set to access a specific property of the displayed items, ToString() may not give the expected text. The fix for this is to use;

GetItemText(Items[e.Index])

Two methods in class 'DarkComboBox' needs to be updated;

• PaintCombobox()
• OnDrawItem(DrawItemEventArgs e)()
