Improved FetchMetadata, Adding Pause state, Fixed "(year)" in title

[TheGeeKing]

Added:

• You can use Trakt to more accurately find the media, get season poster (could add an option in config to choose between show, season, episode poster)
• Displays "Paused ⏸︎ | X%/Y min" when session is paused and shows progress (%) and duration of the media. Close #22

Changed:

• If Trakt is enabled or not, it will try to get tmdb guid to get data from the api and not do a title query
• Removes "(year)" in title. Fix #21
• README.md has Trakt setup indications and configuration values
