Collections are not stored in replapplication.objects anymore, but in
replapplication.collections. This fixes the IDs issue. There was no gain
from storing them in objects.
Completion right after cd should be faster (and should always have been
like that, it was pretty much a bug).
The display of do_ls() should be much clearer. Collections are always at
the end, have ids/title/backend like objects (but using a formatter
would be better than my current hack).
There are still many issues with the current implementation.

* Make the declaration of fct and it in the constructor Collection,
instead of adding them from the outside
* Add a function to flatten a list containing collection (solves the
radioob search crash)
* Better display of collections in the "ls" command (and display both id
and title)
* The "cd" command goes to the root of the path (like the UNIX cd)
* Move the Video object of canalplus in a correct path
* Make Collection iterable
* Add comments to CapCollection
* Cache the result of fct in a Collection; it is only called once
* CollectionNotFound errors can be more explicit by providing a path
* Require utf-8 in collection paths
* Code cleanups
