DynamicData initialization timing and event scripting

[gm9]

I just felt very stupid when I found a Russian version of ProfitUI they distribute on norrath.ru and saw that they solved the issue I (and others here) had with the subclass detection and the timing of the initialization of the subclass dynamic data.

The very simple solution: A Textbox has an OnChange event. /facepalm

Doesn't matter much now that we get OnTextChanged with GU51 but I still thought I'd post that here.

Oh and major negative props to the Russian modder(s) for taking the work here without asking or giving much credit (all I saw was a link back to the "English version") and then not even feeding the fixes they do back to us. That's not how you do it guys, that's bad style.
