Description

In James.java and AvalonMailStore.java, we can replace the HashMap that holds
all of the repositories with a ReferenceMap. The default settings should be
fine. The members are mailboxes and repositores, respectively.

This change should allow James to release un-used mailboxes in times of low
memory.
