Subject: [PATCH] Clear message collections when the window is closed

We don't need to keep them in memory if we're done viewing them,
plus it avoids having to re-render a large collection when we re-open a
conversation. Now that we only load a sensible number of messages at a
time, caching them between usages is less valuable. Removing them from
the collection should free them for garbage collection.
