Add sources for servlet-api
AbstractColletionMigrator - when renaming fields, do it for all documents, not just the first
Migration - allow migrations to be restarted on failure

Add the ability to find the most recent successful migration, rather
than just the most recent migration, and pick up from that point when
starting a migration.  This allows failed migrations to be retried,
rather than just assuming the most recent attempt succeeded.
Up the default timeout for EDiscovery from 30 to 300 seconds
Fix display of UTF-8 message summaries

Make sure that all the responses in all servlets set the output encoding
to UTF-8, so that non-ascii character sets are encoded properly in the
response to the client.
Update to 1.4.1-rc1
Bug 24 - Make sure From_ lines are correct in mbox exports

If the MailFrom entry in the DB is not correct (for example, the
imported email had no MailFrom), then the exported main is not valid
MBOX format.  Work around this by making sure the From_ line in the
exported MBOX file is always valid.
