Adding Spark 1.0.0 download locations
Merge pull request #52 from pwendell/v3

Adding Spark 1.0.0 download locations
Support for r3 instance types.

Amazon's new r3 instances come without EXT3-formatted drives. This patch

as ext3.

Hopefully this will be subsumed later if anyone wants to pick up
SPARK-1079.
