PDO exception on update because prefixed tables cause table to not be found

When updating an existing hour block nothing seems to happen unless you view the JS console. Turns out the request page is throwing a 500 due to a PDO exception because the opening_hours table is not being found. I am using prefixed tables here.

The error occurs in opening_hours_instance_load() line 278 of current (1.2) release. Simple error and fix. The table name is not being wrapped in braces.

So this line:
$query = db_query("SELECT * FROM opening_hours WHERE instance_id = :id LIMIT 1", array(
Should be
$query = db_query("SELECT * FROM {opening_hours} WHERE instance_id = :id LIMIT 1", array(

Thanks for the great module.

UPDATE
Should have done this before posting :-[ I just did a quick scan through the code and opening_hours_cron() appears to have the same issue (I've not actually tested that cron yet) on line: 164 with the $propagate_query assignment. The table name needs to be wrapped in braces. There may be more similar occurrences so I'm giving it a quick scan through and if there are several I'll make a patch.
