Problem: NoteBook add/delete/add page with the same 
name does not work. python2.2/Tix

Example Python Script for reproducing the Bug:

import Tix
import rlcompleter
root=Tix.Tk()
notebook=Tix.NoteBook(root, ipadx=3, ipady=3)
notebook.add('general', label="General", underline=0)
notebook.add('displaymode', label="Display mode", 
underline=0)
notebook.pack()
notebook.delete('general')
notebook.add('general', label="General", underline=0)
la=Tix.Label(notebook.general,text="hallo")
Traceback (most recent call last):
  File "<stdin>", line 1, in ?
  File "/usr/lib/python2.2/lib-tk/Tkinter.py", line 
2261, in __init__
    Widget.__init__(self, master, 'label', cnf, kw)
  File "/usr/lib/python2.2/lib-tk/Tkinter.py", line 
1756, in __init__
    self.tk.call(
TclError: bad window path name 
".135915860.nbframe.general"   

Tix seems nothing to know about the new page
>>> notebook.tk.call(notebook._w,'pages')
'displaymode'

Analysis:
in NoteBook.add() the new "same named" widget will
succesfully created in tk. But it will be immediatly 
removed, if the TixSubWidget is constructed

Solution:
In the Notebook class:
Do mark subwidget "destroy_physically=1". Also
for clearness delete entry from subwidget_list dict.
I dont't know if this is a fine or correct solution
but it works (for me)
