Add an easter egg

[maduranma]

A big piece of software of this kind must have at least one easter egg.

What about this at the beggining of the code?

import sys
if len(sys.argv) == 2 and sys.argv[1] == 'HelloWorld':
    print('You found an egg, I hope it\'s an easter one')

Good idea in my opinion. Taking into account past days:

• the 1 and 2 should be replaced with len(...) (day 2)
• both strings should need to be encoded in another binvals array (day 6)
• ...which needs to be be encoded in another binvals array (day 9)
• the print() statement should be replaced with the C one (day 4)

I'll make a branch.
