python version bug

[Chenfengldw]

In jstorm.py, at first the code checked the python version but in:
if not os.path.exists(JSTORM_DIR + "/RELEASE"): print ("******************************************") print "The jstorm client can only be run from within a release. You appear to be trying to ") \ "run the client from a checkout of JStorm's source code.") print "\nYou can download a JStorm release " print "******************************************" sys.exit(1)
the print function is still in python2 style and will raise bug when using python3.
