Added responsive design & fixed typo in landing page

[bastilimbach]

Important: Do not merge into master!
I added the necessary css to achieve a responsive design and fixed some typos.
I also deleted some unnecessary files.

If you create a "gh-pages" branch and we merge my changes into "gh-pages", GitHub automatically recognizes this as your project landing page. More infos here.
After the creation of the "gh-pages" branch I will change the base branch of this PR so that you just need to click on the green merge button 😉

Also the URL is a bit cleaner with a "gh-pages" branch:

• Before: https://micku7zu.github.io/vanilla-tilt.js/landing/index.html
• After "gh-pages" branch: https://micku7zu.github.io/vanilla-tilt.js

Thanks, merged, fixed some small things and it seems that everything it's working great with "gh-pages".

If you have some way to include the credits in the mobile version it would be great 😄 .
It's important for me to put tilt.js logo too

[bastilimbach]

I thought about including the tilt.js logo beneath the vanilla logo, but I think it would be a little confusing for some people to have two boxes of the same style on top of the page. What do you think? Would it be ok to put the logo and credit of tilt.js at the bottom of the page? (On mobile only)

[micku7zu]

Yes, I think that a footer with the credits, which is visible only on mobile, it would be great.

I'm on it 👍
