Episodes can only be integers

[OussamaDanba]

All major services (FUNimation, Crunchyroll, Daisuki) allow episodes that are non-integers. These episodes are nearly always recaps or specials so the decision can be made to not bother with those episodes. If that's the case non-integers should probably be explicitly ignored otherwise casting to int will cause episode numbers to get improperly converted. This will probably work fine since episode x.y will always be casted to x which very likely already exists but it's something extra to take into account.
