[Glade-devel] [glade-3] Query Popup Dialog "Cancel" button fix.

[bighead users sourceforge net (Archit Baweja)]

Hey ho!

While I was trying to look into bug #157667 (oh yah, I'm looking into
that one), I had the oppurtunity to re-familiarize myself with the code
and found some shortcomings.
The following patch includes following

1) Minor cleanup/fixes (like replacing use of magic numbers in the
middle of the code with named constants).
2) The Query Popup dialog didn't have a cancel button (it used to have
one). Anyway, its back again.

Please review (so I can commit). I'll keep look into that bug fix till
then.
