[FIX] web: add support for discarding lines in o2m

This is not a complete work, but it introduces the basic infrastructure
to properly edit various more sophisticated editing behaviours.

The main focus of this commit is to handle discarding invalid lines in
one2many, potentially asking the user for confirmation.  So, the
relevant methods have to be modified to return some deferred, because
the operation is now asynchronous.
