Fixes GH-45 (https://github.com/spring-projects/spring-integration-aws/issues/45)
S3InboundFileSynchronizer failing when processing through S3 directories - modified approach for splitPathToBucketAndKey to account for the fact that there will be more than one forward slash in the path when subdirectories are used in an S3 bucket. Set up split operation to use the limit parameter to force the bucket identifier into the first element and the remainder of the text (the key) into the second element.
* modified unit test to include subdirectories.
*fixed additional usages of the split operation without the match limit parameter. DRY'd up some code. Cleaned up unit tests.
* added @author annotation at project lead's request.
Add some polishing
