updating pyxhook.py to python3
Converting pyty.py to python3 and handling SIGINT
making __main__() wait for hm thread to join:

Adding hm.join() at the end of __main__() and thus deleting the try:
except: pass in SigIntHandler()
Commenting hm.Hook{Keyboard,Mouse}() as the methods are empty in pyxhook.py
Commenting what I have changed to the code
updating pyty.py hashbang
Renaming SigIntHandler in sigint_handler to follow the naming convention in use in the program
correcting a typo: no argument needed in hm.join()
Deleting unused import PIL
Merge branch 'denischevalier'
updated readme
