Add more metadata to Kodi information pane

[dagwieers]

Describe the feature

Currently the Kodi information pane is showing very limited metadata for our VOD content:

• ListItem.Premiered (episode) -- Date aired:
• ListItem.Studio (episode/oneoff/program) -- Studio:
• ListItem.Tag (episode/oneoff) -- Tags:

whereas we could be showing:

• ~ListItem.Date (episode/oneoff) -- Date:~
• ListItem.DateAdded (episode/oneoff) -- Date added:
• ~ListItem.Duration (episode/oneoff) -- Duration:~
• ListItem.Playcount (episode/oneoff) -- Play count:
• ListItem.LastPlayed (episode/oneoff) -- Last played at:
• ListItem.DBTYPE (episode/oneoff/program) -- Media type:

The code was merged into the master branch and will be released with Kodi Matrix.
