Monster class

So i added a monster class but I have seen some one added an opponent
class in character which is similar to mine. Thank for the people who
is generous doing my work.I did not add monster class into the main fun
on main.py  in case  monster crashes the whole program, Therefore you
could not see the monster on the screen for now. The program works fine
on my computer now  I will keep on working on this. BTW, bmp files have
been converted into png file on MAC, which does not work on pygame.
Thus, I added several bmp file into image folder. But I did not do
anything to __init__.py
spell init incorrectly sorry...
so basically i make the monster class similar to the character

did not do much modification to the main fun . The game works on my
computer
Try run on your computer and let me know if I crash the program...
