Switch to transition_post_status instead of save_post

Scheduled posts don't get any love because the save_post action isn't fired by wp_transition_post_status().

Switching to the transition_post_status action instead of save_post fixes this problem. Since that action provides the old and new statuses, it also eliminates the need for get_post_status() and lets you move the status check logic to the start of the function. Autosave doesn't trigger either, so that check can be eliminated.

I love the plugin, but my scheduled posts weren't feeling the love.

And for consistency, there's a support forum post for this too: http://wordpress.org/support/topic/url-isnt-generated-for-a-scheduled-post
