Begin rewrite. I'm getting some error loading the CSS,

and I still have to write all the JavaScript to make it more than a
pretty face.
Restore original `inserthtmlSkelly` function.

I'll have to rework it later.
Fixed loading error (Thanks @njx!)
Disable toolbar image, HTML, CSS, and styling fixes,

activate menu and keyboard shortcuts
HTML cleanup, connect dialog closing to _performActions()
Add HTML elements for insertion, implement image size values

The former is yet untested, but there's shouldn't be anything that would
stop it from working once the code is in place. I chose to do the image
sizes first because of adobe/brackets#6707, which inspired this rewrite.
Cosmetic tweaks
Forgot the CSS
Update package.json before time, kill vertical scrollbar in dialog
Elements are now added to the document! :smile:

However, this is still much to do, as you can see in the comments. Also,
I did a lot of stuff. So much that I won't care to list it all. I'll let
that be GitHub job. :P
Fix image size scoping error, indentation
Relocate HTML document
Remove CSS for toolbar button
All that is left now is the README....
Update README.m
