Extend the recognition algorithm (regex)

[MeGaNeKoS]

Extend the recognition algorithm. Since A lot fansub having this version scheme. Probably if you want to add it as well.

Not work:
 - [Judas] Chuunibyou S1 - NCEDv2.mkv # season 1 ending
 - File: [Judas] Chuunibyou S1 - S02.mkv  # season 1 special eps 2
 - File: [Judas] Clannad - S01OVA01.mkv  # season 1 ova eps 1
Work:
 - [Judas] Chuunibyou S1 - NCED v2.mkv
 - [Judas] Chuunibyou S1 - SP02.mkv
 - [Judas] Clannad - S01 OVA01.mkv

If you would add this, I can search for the files using those scheme.
For now, i just add the check on mine manually before be parsed by anitopy.

For the S1 -S02, i think we can check if there's 2 season, but no episode. Than we could assume it season x special eps y.
