Sean Owen e07baf1412 [SPARK-17001][ML] Enable standardScaler to standardize sparse vectors when withMean=True 
## What changes were proposed in this pull request?

Allow centering / mean scaling of sparse vectors in StandardScaler, if requested. This is for compatibility with `VectorAssembler` in common usages.

## How was this patch tested?

Jenkins tests, including new caes to reflect the new behavior.
