In my humble opinion, Courtney should indeed be included as a Companion as she has taken several trips on the TARDIS and assisted the Doctor in working out problems - notably in Kill The Moon.

Why not just have a line in her entry that says something along the lines of "With her appearance in Kill the Moon, Courtney fulfils all requirements of a Companion"? There - job's a good one

If you want to be pedantic about things, you could claim that the TARDIS herself is a companion of the Doctor - or the Doctor is a Companion of the TARDIS (depending on who stole who).
