Glade urgency_hint property

[Ian Lewis]

I recently created a patch for a bug which contains a modification to a
glade xml file. I changed the glade file by using the glade editor and it
added some 'urgency_hint' elements and a some last_modification_time
attributes. I figured glade had it's stuff together and this wouldn't
present any issues but Charles Day brought it up and there seems to be some
instances in SVN where these attributes were removed deliberately.

Is this a problem in term of backwards compatibility in some way? If so, is
there a way to tell glade to respect backwards compatibility and not add
these attributes? Editing the glade files by hand is a pain and seems like
it partially defeats the purpose of using glade.
