persistent filter, order and selection in configuration screens

[GoogleCodeExporter]

in configuration screens the filter, order and selection are persistent now.
major use cases:
- view codes in one user maintained list by using a filter. 
  is a workaround for: Issue 6: good screen for User codes by type
- in composite routes use filter to select this route, than sort on seq.
  is a workaround for: Issue 3: routes should be sorted on routeID,seq
- works  nicely with search function.
  This makes the maintenance of larger codelists easier.

is not available in django 1.3
added middleware-function to do this, middleware should be added in settings.py

works for django 1.1.1
