Rename work posting buttons
Description
The current situation
When you create an entirely new work, the options are currently:
Preview | Post Without Preview | Cancel
If you're working with an exisiting draft, another option is added:
Save Without Posting | Preview | Post Without Preview | Cancel
The problem
The repetition of "Preview" and "Post[ing]" can cause unnecessary confusion over which button to choose. In the words of a user:
Whenever I want to preview, I hesitate over which instance of "Preview" to click on, and twice now I’ve clicked on the wrong one, posted a work that wasn’t ready, and had to delete it. Plus my subscribers presumably got notified.
The proposed solution
To eliminate this confusion, we can remove the overlapping words.
For an entirely new work, the options would be:
Preview | Post | Cancel
And for an existing draft, the options would be:
Save As Draft | Preview | Post | Cancel
