Update README.md

Updated files with an accurate list of task included in the redesigned S3NAntTask project.
Inadvertantly changed the file on the wrong branch. Reverting file to its original state.
adding new Copy file task to copy a files in S3
Enhancements:
1) New Task: amazon-s3-copyFile that will allow you to copy a file between buckets within S3
2) Incorporated a string (bucketName) requirement to method BucketExists to allow for validating the existence of more than one bucket.
3) Incorporated a string (fileKey) requirement to method FileExists to allow for validating the existence of multiple filenames.
4) Formatting changes on output statements

Bug Fixes:
1) Added a test to make sure a bucket exists before attempting to delete it
2) Corrected an issue where you were unable to delete files if they were inside a sub directory of the bucket
3) Added back in the CreateBucket method to the deprecated 'amazon-s3' Task to more closely mimic the original behavior of this Task
