Merge pull request #567 from ScrapCodes/style2.

SPARK-1058, Fix Style Errors and Add Scala Style to Spark Build. Pt 2

Continuation of PR #557

With this all scala style errors are fixed across the code base !!

The reason for creating a separate PR was to not interrupt an already reviewed and ready to merge PR. Hope this gets reviewed soon and merged too.

Author: Prashant Sharma <prashant.s@imaginea.com>

Closes #567 and squashes the following commits:
