beos: Better implementation of NSIconTextControl for the url bar

Browse Source 
Instead of adding a child view we draw the bitmap over the child.
Fixup the TextRect also in Draw() which is called just before the
TextView's Draw().

It flickers a little less, and also respects the background color of
the text control when using a desktop theme.

Also drop a useless dynamic_cast.
