Log:
  lualoader: screen argument fixes
  
  screen was also guilty of not-so-great argument names, but it was also
  guilty of handling color sequences on its own. Change those bits to using
  the color module instead.
  
  As a side note, between color and screen, I'm not 100% sure that returning
  the color_value is the right thing to do if we won't generate the escape
  sequences. This should be re-evaluated at a later time, and they should
  likely return nil instead.
