Creating a category on the add/edit post page and pressing enter saves the post

[gilbitron]

When you create a category on the add/edit post screen and hit "enter" the expected behaviour is to create the category. Instead the post is saved and the category is not created.

This diff fixes the issue on the Edit Post screen but not on the Add Post screen.

I've noticed this too - tripped me up several times.

This could also be applied to the post date/time inputs as I've seen the same thing happen there a few times.

fixed "enter" keypress on both publish date and new category text fields, works in both new / edit for post / page

removed "console.log"

moved $.fn.submitTarget to post.dev.js, use generic instead of explicit jQuery object
