v18 - Extended Artwork Loading

Hello @rmrector

PR13859 - https://github.com/xbmc/xbmc/pull/13859
Build - KodiSetup-20181023-c77874c5-master-x64

I installed the above build to test out the newly merged PR. I used my existing NFO Files and local artwork on a portable install and tested with Transparency! and Aeon Nox Silvo skins.

I added the following to my advancedsettings.xml file

	<videolibrary>

		<tvshowextraart>

			<arttype>banner</arttype>

			<arttype>characterart</arttype>

			<arttype>clearart</arttype>

			<arttype>clearlogo</arttype>

			<arttype>discart</arttype>

			<arttype>landscape</arttype>

			<arttype>logo</arttype>

		</tvshowextraart>

		<tvseasonextraart>

		</tvseasonextraart>

		<episodeextraart>

		</episodeextraart>

		<movieextraart>

			<arttype>banner</arttype>

			<arttype>clearart</arttype>

			<arttype>clearlogo</arttype>

			<arttype>discart</arttype>

			<arttype>landscape</arttype>

			<arttype>logo</arttype>

		</movieextraart>

	</videolibrary>	

All Basic and Extended artwork was loaded and visible using the different views from the two installed skins. Checking the Choose Art screen for a number of Movies and TV Shows also showed artwork had been loaded correctly, with two exceptions.

1. I have been using Artwork Beef, so I had renamed all my disc images to discart in accordance with your requirements. Using this advancedsettings.xml method, discart is not recognised by the skins. Though the discart image is loaded, it is not displayed and I have to rename the files back to disc and add the new art type disc. Is there a workaround for this?
2. I added banner to the tvshowextrart. I have duplicated banner entries in the Choose Art screen.

I have not gone to the extent of applying specific season and episode art to my library, except for season posters which is standard. Where is Kodi expecting to see season and episode artwork? In the TV Show folder or is there a requirement for Season and Episode folders to use this (assuming skins support it). Depending on its location, how should it be named?

What does this mean for Artwork Beef?

Thanks for yours and @DaveBlake 's work on this Image may be NSFW.

Oops, forgot to enable discart in Settings in the Aeon Nox Silvo skin.
Transparency! still requires disc.png
