Adding 2 features:
- Enhancing episode matching - e.g.:5x03 (use case: "Downton Abbey 5x03
720p HDTV x264 FoV")
- Enabling title mapping (use case: "CSI S15E02 720p HDTV X264
DIMENSION")

To add a title mapping, just add another section in legendastv.ini:

[Mapping]
CSI = CSI: Investigação Criminal
