Metacat

Added OAI-PMH chapter that was contributed by Duane Costa from LTER.

Simplify setReplicationStatus() to not call updateReplicationMetadata() if a replica doesn't exist. Just create it and update the system metadata, which we already have a lock for.

Minor null checks to avoid NPEs when calling replicate()

Don't throw a NotAuthorized exception in isAdminAuthorized() - just return false.

do not download and save remote data resources which are HTML but are not expected to be such (login or info/splash pages before data content).

Fixed formatting.

Moving Metacat Sphinx RST documentation from docs/dev to docs/user directory.

Merged most recent changes from trunk into the RST converted version of the Administrator's Guide. Now the Sphinx/RST version is up to date rlative to the most recent word document, and is now the active copy. The MS Word document will be deprecated and removed. All future changes should be made to the RST version.

Update the CN methods to throw a VersionMismatch where the API changed (where serialVersion is a required parameter). These were previously throwing an InvalidRequest exception.
Change the exception handling for calls to Hazelcast to catch a RuntimeException (not Exception) so we don't catch exceptions that we purposefully throw....

Use a Logger instead of System.out for SystemMetadataMap.
