[TV] Cleanup retrieval of media query and title

This PR should simplify how search queries are accessed by providers. I've updated all the providers to support this but have only fully tested these changes with IPT and NZBIndex, so there is small chance of provider specific bugs.

#### Overview of changes
 - Moved ```searcher.get_search_title``` event to ```library.query```
 - Identifiers on the ```library.query``` event **default to included**
 - Added ```library.title``` event to return the title of a movie or show without year and identifiers
 - **(Movie)** ```include_identifier``` parameter renamed to ```include_year```
 - **(Show)** Added ```condense``` parameter to provide the ability to disable title condensing *(via the QueryCondenser library)*
