QXEmbed reparent patch

[Till Krech]

Hi,

I discovered a problem in QXEmbed (kdelibs/kdeui/qxembed.cpp).
QXEmbed is now also used by the java applet server and the nspluginviewer.

Problem:
http://www.shockwave.com embeds several flash movies. Although 
QXEmbed::embed() is called, the movies are not always embedded but appear in 
a toplevel window managed by the windowmanager.

I think that this is the same problem why applets are not always embedded when 
running konqi under sawfish/gnome.

The trick is, to retry to XReparentWindow the window for up to 50 times with 
slight delays (usleep(1000)) and look if it has already the required parent 
with XQueryTree.

Could you please look at the attached patch, if it solves the problem or if it 
is just a workaround. Some Xlib knowledge required.

regards, till
