Adding in emenies

For adding the enemies I will add in multiple sprites of the same image

I added the Enemies in as a group in random areas into the map just like i did with the Diamonds and astroids.
I have created 7 aliens to be in the level.

 The code I have implemented randomly sets the aliens into a group that is named aliens. i have also included a tweening function for all of the aliens that makes them seem as they are disappearing into the darkness and reappearing .
