Adding new post shortcut

[kkoppenhaver]

This is the first pass at adding a new post shortcut as identified in #2.

Because there seems to be some precedent with using Ctrl + Option (Mac) and Alt + Shift (Windows) for shortcuts in the WordPress editor, I've opted for Ctrl + Option + N to be the Mac shortcut and Alt + Shift + N to be the Windows shortcut.

This code listens for either of those key combinations to be pressed and then clicks the existing New Post button. This may be possible to use window.location.href or something like that instead of simulating a click (especially if #7 gets merged and the button isn't always new post), but I think it should work for now.

I tested this briefly and it works great. Thanks for adding this @kkoppenhaver! I'm sorry it took me to so long to get to it. 😅 I've just left one comment about an import.

My other thought would be, should we add some sort of visual feedback when the keyboard shortcut is used, so that folks know it's actually working? You can see it working when you see the browser is loading a new page, but that's possibly a bit too subtle. What do you think?

Although as I'm thinking about it, perhaps there should be feedback regardless of how we press the button. So I can add that as a separate PR. Once you've reviewed the requested change on this, we can merge. :)

Thanks @aurooba, I've taken care of that change and updated both README files to move this from an "upcoming feature" into the supported features list.

Congrats on the podcast launch, by the way. I've been a listener since episode 1 :)
