Support touch events on desktop + Add GH demo page 

Hey there, this PR contains a few minor changes related to the examples. I wanted to have an online example and didn't found one. So, to create one, here're the changes I made on my fork:

- Added [FingerBlast.js](https://github.com/stephanebachelier/fingerblast.js/blob/master/dist/fingerblast.js) to examples to support touch events on desktop.
- Created a gh-pages branch from master.
- Added a `README.md`, providing links to the examples (note: those links would need to be updated to fit **your** GitHub page URL!).

Also, I removed references to the viewpager.com domain (since it seems to be no longer maintained).

Just thought to share with you. If you like to, feel free to merge/adapt my changes. Otherwise just close this PR. :)

Cheers
