move .js and .css files out of the root

[NovemLinguae]

Move twinkle.js, morebits.js, CSS files, etc. out of the root. The root directory should be config files and readmes only.

Wikimedia also does this. JS files are always all placed in a directory called /modules/ (or sometimes a subdirectory with a different name, the other name escpaes me at the moment). But never in the root.

Fixes #2078

To test:

• npm start
• perl deploy.pl - test by deploying to testwiki

Maybe:

• put the old modules in a subdirectory? modules/menuItems/*.js or something?

After thinking about this a bit more, I think I do want to have a subfolder for the Twinkle modules, but I also want to avoid an ugly modules/modules. Perhaps src/modules would be a good way to do it?

src/
   |--morebits.css
   |--morebits.js
   |--twinkle.css
   |--twinkle.js
   |--twinkle-pagestyles.css
   |--modules/
      |--twinklearv.js
      |--twinklebatchdelete.js
      |--twinklebatchprotect.js
      |--etc.

@siddharthvp, can I get a second opinion on that?

Putting everything under src/ looks good to me and is consistent with modern JS projects. In fact, I had a branch locally that made the same change but didn't get around to pushing it.
