- Fixed the thumbnail loading issue on paginated pretty URLs.

The bug was relative media paths like media/thumbs/... resolving under 
routes such as /v/<slug>?page=2 or /search/<query>?page=2. I added 
public_media_url() in 
[includes/db.php](/Users/tyemeclifford/Documents/GH/mediaplayer/includes/db.php) 
and updated public thumbnails, posters, and local player sources in 
[index.php](/Users/tyemeclifford/Documents/GH/mediaplayer/index.php), 
[catalogue.php](/Users/tyemeclifford/Documents/GH/mediaplayer/catalogue.php), 
and [embed.php](/Users/tyemeclifford/Documents/GH/mediaplayer/embed.php) 
to use root/base-aware URLs.
