Deleted projects are not removed

[superlou]

In cablecast_sync_projects, there is no mechanism to remove a project that has been removed on the backend.

wp-cablecast/includes/sync.php

Lines 375 to 393 in bcabf82

	function cablecast_sync_projects($projects) {
	foreach ($projects as $project) {
	$processed = cablecast_replace_commas_in_tag($project->name);
	$term = term_exists( $processed, 'cablecast_project' ); // array is returned if taxonomy is given
	if ($term == NULL) {
	wp_insert_term(
	$processed, // the term
	'cablecast_project', // the taxonomy
	array(
	'description' => empty($project->description) ? '' : $project->description,
	)
	);
	} else {
	wp_update_term($term['term_id'], 'cablecast_project', array(
	'description' => empty($project->description) ? '' : $project->description,
	));
	}
	}
	}

If we had a way to keep track of which terms still exist, is it safe to call wp_delete_term on any remaining terms? Is there any chance that $projects may not contain all projects in Cablecast due to a server response error?
