On "New Episode" Prefill "season" and possibly also "episode" fields
When adding many episodes, e.g. on existing podcast series, filling in the same season and remembering the correct episode numbers is quite bothersome.
It would be great if the season field could be prefilled with either a) the number that had been added last (better strategy) or b) the highest number ever used (easier to get).
Also prefilling the episode number by using the highest existing number +1 is a good guess for an automatic population of the fields.
