Allow user to disable 'long press to add media to playlist'

[iccub]

We have to implement new settings in playlist screen.

Setting name Enable Long Press
Footer When enabled, you can long-press on most video/audio files to add them to your Playlist.

This ticket will also change Add to playlist toast footer
to When enabled, a bar will automatically show on most media websites making it easier to add those video/audio files to your Playlist.

This setting should be enabled by default.
