Title parsing fails to often. Here is some tweaks to make it more efficient.

Tasks:
- [ ] Remove language tags in movie parser (FRENCH, GERMAN, TRUEFRENCH, etc ...)
- [ ] Remove file extensions in movie parser (iso, rar, zip, ...)
- [ ] Add more qualities (dvix, ...)
- [ ] Make a Unit Test with various entry titles (scene tagging, dirty tagging, no tagging at all, ...)
- [ ] Support custom configuration through a "titleparser" plugin

If you have other ideas, we can talk about it here ...
