- Done. The media platform now tracks sources as either local uploads or remote URLs.

Changed:
[includes/db.php (line 
43)](/Users/tyemeclifford/Documents/GH/mediaplayer/includes/db.php:43) 
adds source_type and source_url, with an automatic migration for 
existing SQLite databases.
[admin/add.php (line 
260)](/Users/tyemeclifford/Documents/GH/mediaplayer/admin/add.php:260) 
and [admin/edit.php (line 
383)](/Users/tyemeclifford/Documents/GH/mediaplayer/admin/edit.php:383) 
now let each source be an upload or an external URL.
[index.php (line 
226)](/Users/tyemeclifford/Documents/GH/mediaplayer/index.php:226) and 
[embed.php (line 
193)](/Users/tyemeclifford/Documents/GH/mediaplayer/embed.php:193) 
resolve playback URLs based on where the source lives.
[catalogue.php (line 
79)](/Users/tyemeclifford/Documents/GH/mediaplayer/catalogue.php:79) now 
has public search for published videos only.
[README.md (line 
63)](/Users/tyemeclifford/Documents/GH/mediaplayer/README.md:63) 
documents local vs remote sources and public search.
