Update to the tools scripts:
 * Update to envDefaults: if environmental varialbe ONOS_CELL is set,
   the load it, so its variables can be used by other scripts

 * Modifications inside tools/dev/bash_profile:
   - Update the setting of JAVA_HOME so it works for Ubuntu with
     OpenJDK-1.7
   - Removed "." from being added to the PATH, because it is a security hole
