#85 No way to access the common prefixes found in listBlobs

[Anonymous]

BlobContainer.listBlobs with combineCommonPrefixes set true tries (and fails, see bug 3301556) to get the common prefixes as determined by Azure using the delimiter "/". This information is however not exposed through the BlobContainer API, even though the documentation of the listBlobs methods says it should be - "The list of blob properties and common prefixes".
Therefore I propose changing the return type of listBlobs from Iterator<IBlobProperties> to ListBlobsResult, which seems to be the type of the container that the full result is gathered in anyway.
