opening Preferences dialog twice throws an exception

[Ákos Gyimesi]

It happens only if the first dialog was closed with ESC or delete_event (not by pressing OK/cancel).

Traceback (most recent call last):

  File "/crypt/home/akos/src/pyroom/basic_edit.py", line 167, in key_press_event
    self.keybindings[event.hardware_keycode]()

  File "/crypt/home/akos/src/pyroom/preferences.py", line 316, in show
    self.dlg.show()

AttributeError: 'NoneType' object has no attribute 'show'

I think the error here is that we initialise the preferences dialog outside
the function that calls the preferences dialog. This means that once you
have killed it the object doesn't exist anymore - so object.show makes no
sense.

I will take a look at it later and see if there is something that can be
done.

I fixed the bug, but for some reason my "bzr push" request got stuck :( I attach the output of "bzr diff" (until I get more experience with bazaar)

In interface.glade the only modification I made was to add a new signal handler (on_close) on dialog-preferences/delete_event.
