[Seaside] Suggested extension for WASelectTag

[Paul DeBruicker]

Hi Joachim,

I don't think you missed an existing way to set an attribute on a select tag
option.  Other than iterating over the options like in e.g.
WAInputElementContainer>>#renderSingleSelectionCustomOn: I don't know how to
set them. 


Seems like your method is more convenient than iterating over the option
tags.  I'd add it for sure.
