Breaks upload for other plugins

This plugin takes over all file uploads called ‘file’. This breaks numerous other plugins.
if (isset($_FILES['file'])) { is run directly on the admin_init action. The field should at least be prefixed with hypeanimations_ or ideally happen in a different context then the admin_init action, e.g. a separate wp_ajax_hypeanimations_files action.

Also, the plugin defines global variables like $version and $table_name – which are quite generic names and will most likely cause issues somewhere.
