Spell check the title field

[MikeBeas]

When auto-tweeting your newest posts, the title is often the only thing that's included. The inability to spell check the title essentially means that the first impression people will get of your post is the possibly the worst part (the typos).

Then consider that even if you fix the typo and the tweet, the mistake will likely live on forever in the slug if you haven't changed that from the default. Not a great situation.

The option to spell check the title field (enable standard browser-based text field spell checking, if nothing else) would help ease this problem quite a bit.

This seems to be browser dependent or maybe Chrome can be set to always check <input type="text"> fields. Agree that title spellcheck should be enabled for all browsers, if possible.

Editor: enable spellchecking of the post title field on the Edit Post screen. Props marsjaninzmarsa, fixes #30338.
