tagging the 1.2.6.6 minor temp release.

Properties are loaded using the current thread's classloader by default.
When a config file is not found a descriptive error message is printed to the logs.
Made an interface for the cache manager to improve testability.
Auxiliaries are assigned a cache manager and the lateral TCP has a settable source id, so it can be tested.
Increased JGroups version to 2.2.8.  It works again.  The old JGroups didn't work for unknown reasons.
Cleaned up some javadocs.
Improved info level logging for TCP lateral.
Added configuration properties xdocs for TCP lateral, indexed disk, and memory cache.
Created concurrent tests for TCP lateral to verify correct region behavior.
Made BDBJE work with new auxiliary changes.
UDP discovery no longer activates if the lateral type isn't TCP.
Reduced lateral get timeout to 1 second, rather than 10.  We still need to disable gets when a timeout occurs.
