Python2 to Python3

To make HasyUtils compliant with Python2 and Pytrhon3, these changes had to be done:

 print "..."              -> print( "...")
 print "...", a           -> print( "...%s" % a)
 print "..." % a          -> print( "..." % a)
 print _sys.exc_info()[0] -> print(_sys.exc_info()[0])
 print repr(e)            -> print( repr( e))tel
 print "...",             -> sys.stdout.write( "...") sys.stdout.flush()
 except Exception, e:     -> except Exception as e
 u'...'                   -> '...'
 a in hsh.keys()          -> a in list( hsh.keys()) 
 hsh.has_key( kName)      -> kName in hsh
 import TgUtils           -> from . import TgUtils
 0777                     -> 0o777
 izip( a, b)              -> list(zip( a, b))
 sys.exitfunc = exitHndlr -> atexit.register(exitHndlr) import atexit
 import thread            -> import _thread
 import __builtin__       -> import builtins
 from OtherUtils import * -> from HasyUtils.OtherUtils import *
 hsh.iteritems()          -> hsh.items()
 os.write( fh, 'abc')     -> if sys.version.split( '.')[0] == '3':
                                 os.write( fh, bytes( 'abc', 'utf-8'))
