Add option to delete media (#1014)

## Description
Adds a setting to enable "Media management" which adds a context menu
item to delete media. This is accessible using either the More button or
long clicking.

You can delete episodes, seasons, series and movies/videos.

If order for the option to appear the current user must have server-side
settings for "Allow media deletion from" enabled for the library and the
in-app setting under Settings->Advanced Settings->"Show media management
options".
