Add container names to the list of forbidden names when adding/renaming molecules or reactions

[Yuri05]

On the other side, we don't prevent that a molecule is named as a top-container of the spatial structure (or e.g. Events).
So I can name my molecule e.g. Neighborhoods and create a simulation with this. The molecule is then merged with the corresponding container in the simulation (which produce the weird views below).
Funny enough - such a simulation can be even run (at least in the simple case without reactions, transporters etc. - did not check what would happen in these cases).

So we should at least prohibit that a molecule is named as a top container of the spatial structure or Events.
