Add screenshots

[dagwieers]

This PR includes:

• Screenshots for the VRT.NU addon
• Move icon and fanart to resources/images/

The screenshots are 720p images reduced in size using:

convert -sampling-factor 4:2:0 -strip -quality 85 screenshot-01.orig.png screenshot-01.png

But still quite large, however they compare in size with screenshots of other plugins.

This fixes #107

[dagwieers]

Size difference is considerable, almost 10x larger:

-rw-rw-r--. 2 dag dag  290358 26 mrt 20:08 plugin.video.vrt.nu-1.7.0.zip
-rw-rw-r--. 1 dag dag 2351111 27 mrt 15:26 plugin.video.vrt.nu-1.7.0-15ae565.zip

[dagwieers]

Shrinking 50% (so reducing to 360p) using:

convert -sampling-factor 4:2:0 -strip -quality 85 -resize 50% main-menu.png screenshot-01.png
convert -sampling-factor 4:2:0 -strip -quality 85 -resize 50% video-listing.png screenshot-02.png
convert -sampling-factor 4:2:0 -strip -quality 85 -resize 50% live-tv.png screenshot-03.png

gives:

-rw-rw-r--. 2 dag dag 290358 26 mrt 20:08 plugin.video.vrt.nu-1.7.0.zip
-rw-rw-r--. 1 dag dag 850430 27 mrt 15:31 plugin.video.vrt.nu-1.7.0-15ae565.zip

Why shrinking?
My eyes need 1080p
If there are size limitations for the repository, maybe pngquant can provide better quality with lower file sizes.

Its only visible in the information about the addon directory. I really doubt alot of people will care about the quality. (i only checked it from laptop screen though)

[dagwieers]

@mediaminister It's a tradeoff, I did not want the screenshots to take 90% of the size of our codebase. But it is true that 360p is very blurry on 1080p in Kodi itself. Still I wonder how much people actually click on the screenshots in Kodi. But I am all for higher quality with low file sizes so maybe we can do better. (That is why I shared the commands)

• I made the screenshots in 720p on purpose, hoping that shrinking would lead to better results
• I used Dutch language as that's what most people will be using anyway

[dagwieers]

I just tested with pngquant and it's a very big improvement. Size are somewhat larger, but still 720p.

[dagwieers]

After tweaking and testing a lot of options and combinations, I think I am the most satisfied with this tradeoff using:

pngquant --posterize 0 --quality 65 --speed 1 --force live-tv.png

This results in:

-rw-rw-r--. 1 dag dag 290202 28 mrt 04:15 plugin.video.vrt.nu-1.7.1.zip
-rw-rw-r--. 1 dag dag 684180 29 mrt 01:39 plugin.video.vrt.nu-1.7.1-ce06cce.zip

So that is my proposal, see #107 for the images.

[dagwieers]

Next up is improving the addon descriptions, the README intro, etc.

[pietje666]

Im fine with any decision about the screenshots btw

[mediaminister]

Maybe jpeg is more efficient than png for screenshots with video stills
