* Created TACHYON_CLASSPATH to hold a dynamically generated classpath.
* Updated shell scripts to use TACHYON_CLASSPATH
* Added HADOOP_HOME to point to a local hadoop installation.
* Generate Tachyon + Hadoop CP if HADOOP_HOME is defined
* Updated the default JAVA path in linux to the generic symbolic link (will support most JREs without additional config)
Use a generic method to establish the hadoop classpath.  Requires hadoop command in classpath and works with 1.x and 2.x
Revert the JAVA_HOME setting.

fix JIRA TACHYON-2: Remove warning in mvn package
createNonRecursive() should throw exception if parent directory doesn't already exist,  which is extremely important for HBase to do fencing of dead region servers properly.
fix issue 55 in JIRA:
InetSocketAddress may resolve "localhost" to network address like "192.168.*.*".
Test failed in TachyonFSTest.toStringTest:421 expected:<...achyon://localhost/1[92.168.172.43]:19998> but was:<...achyon://localhost/1[27.0.0.1]:19998>
Treat the hadoop classpath as an optional configuration item.  User must uncomment a section in the tachyon-env.sh to add entries for hadoop libraries.
