Merge pull request #1114 from snoopycrimecop/merge/dev_4_4/submodules

Update dev_4_4 submodules
Make checksum safe against raw file store save() returning null.
Fix long-missing DELETE EventLogs

This check has been wrong throughout the 4.4 series.
If this is the last element, then EventLogs should be
raised for every OriginalFile deleted. This has not
been happening. (Very sadly)

This should be rebased onto dev_4_4
Fix cached thumbs bug in SPW. See #10827
Fix NetworkChecker hangs on Linux (See #10824)

Rather than attempting to connect to o.org.uk from Linux clients,
we attempt to use the Java 1.6 classes via reflection. If the
client is running on Java 1.5, the network is always assumed to
be up. This may cause deadlocks on changing networks for
Linux+Java 1.5 users, which will have to be clearly outlined in
the release notes.

For the more far more common cases, however, this should be work.
