#486034 by drewish: Stop rounding all times to hours so 30 minute programs show up in current program block.

Realized that the streams weren't being displayed correctly by the views handler. Refactored this into its own station_schedule_unserialize_streams() function.

Better UI when editing the program, now it tells you you need to save before you can schedule. Also redirects back to the edit form after scheduling.

#195764 If no archive is setup, error about Unknown column 'station_schedule_item.archive_links' appears.

#193212 Update from 5200 fails because station_schedule_insert() references fields added in later updates.

- $_POST['edit'] is now $_POST.
- station_hour_name() has been removed.
- station_get_program_at() needs a schedule nid.

The album nodes weren't loading the node type information to correctly build the body form elements.
