Bug fix in master build

Improved organization of scheduling packages.

This commit does not change any code -- only file organization.
Please let me know if there was some masterminded strategy behind
the existing organization that I failed to understand!

There are two components of this change:
(1) Moving files out of the cluster package, and down
a level to the scheduling package. These files are all used by
the local scheduler in addition to the cluster scheduler(s), so
should not be in the cluster package. As a result of this change,
none of the files in the local package reference files in the
cluster package.

(2) Moving the mesos package to within the cluster package.
The mesos scheduling code is for a cluster, and represents a
specific case of cluster scheduling (the Mesos-related classes
often subclass cluster scheduling classes). Thus, the most logical
place for it seems to be within the cluster package.

The one thing about the scheduling code that seems a little funny to me
is the naming of the SchedulerBackends.  The StandaloneSchedulerBackend
is not just for Standalone mode, but instead is used by Mesos coarse grained
mode and Yarn, and the backend that *is* just for Standalone mode is instead called SparkDeploySchedulerBackend. I didn't change this because I wasn't sure if there
was a reason for this naming that I'm just not aware of.

EC2 SSH improvements

Add mapPartitionsWithIndex

some minor fixes to MemoryStore

This is a repeat of #5, moved to its own branch in my repo.

This makes all updates to   on ; it skips on synchronizing the reads where it can get away with it.

Smarter take/limit implementation.

Fix spacing so java.io.tmpdir doesn't run on with SPARK_JAVA_OPTS

Refactor FairSchedulableBuilder

1. Configuration can be read from classpath if not set explicitly.
2. Add missing close handler.

Fix PR926 local properties issues in Spark Streaming like scenarios

Add "org.apache." prefix to packages in spark-class

After unit tests, clear port properties unconditionally

Lacking this, the if/case statements never trigger on Spark 0.8.0+.
