[rfc][icedtea-web][policyeditor] Parent-window searching fix

[Andrew Azores]

Hi,

I came across this hunk while working on another patch and thought it 
deserved a bit of cleanup. Rather than manually searching for the first 
parent component which is a Window by looping and checking the parent's 
type, a SwingUtilities utility method is simply used instead. If the 
Javadoc on this method is to be trusted then the semantics are 
identical, and it seems to work fine anyway.

Thanks,
