ComboBox Error
The ComboBoxChangeEvent does not appear to be working (or in) the latest version of Nigui.  I had to go back to when ComboBox was first added in order to get the functionality back (I may not have needed to regress that far back, but I did that just to make sure).  

I don't know if this was on purpose if combobox is to be deprecated or if this is bug, just thought I would mention.

Using the latest dev Nim branch on Arch.
