Fix typo in print function

[snovvcrash]

Fixed typo in print function. The printc function was used instead of print which was causing the following exception to be raised:

Traceback (most recent call last):
  File "./gateway-finder-imp.py", line 494, in <module>
    addresses = load_objects_new(args)
  File "./gateway-finder-imp.py", line 95, in load_objects_new
    printc('[-] \t%d. This line does not contain valid MAC: "%s"' % (i,paint_s(lines[i],'orange')) )
TypeError: printc() missing 1 required positional argument: 'color'

Please save everyone some heartache and merge this!
