New Revision: 1414598

URL: http://svn.apache.org/viewvc?rev=1414598&view=rev
Log:
Merged latest changes from my fork mainly for OAK-455, OAK-459, OAK-477

-Added TimingWrapper for OAK-455 which can be used to time MicroKernel calls
-Removed oak-mongomk's unnecessary dependency to commons-io
-Optimizations and fix for OAK-459 to FetchNodesAction
-Optimization for OAK-455 to CommitCommand to not fetch commits unnecessarily
-Optimization for OAK-455 to GetNodesCommand to not fetch commits unnecessarily and also to set depth for FetchNodesAction call.
-Optimization for OAK-455 to NodeExistsCommand to fetch the leaf-to-root nodes in one FetchNodesAction call.
-Initial fix for OAK-477 in JsonUtil, MongoUtil and CommitBuilder along with the test in MongoMKCommitAddTest
