Random Changes and Enhancements (#1819)

* When skipping over folders in a scan, inform the ui

* Try out new backout condition for library watcher.

* Tweaked the code for folder watching to be more intense on killing if stuck in inotify loop.

* Streamlined my implementation of enhanced LibraryWatcher

* Added new extension method to make complex where statements cleaner.

* Added an implementation to flatten series and not show them if they have relationships defined. Only the parent would show. Currently disabled until i figure out how to apply it.

* Added the ability to collapse series that are not the primary entry point to reading. Configurable in library settings, only applies when all libraries in a filter have the property to true.

* Exclude from parsing .@_thumb directories, a QNAP system folder.

Show number of items a JumpKey has

* Refactored some time reading to display in days, months, years or minutes.
