Remove mobile conditions

Remove a lot of mobile behavior, which as smartphones gets bigger screens it not wanted behavior.

Removing scroll on viewport is not something you want as it also happends on a iPad for an example.
The window.scrollTo does not work on iOS7 anymore, so that is also useless now, also because it will not scroll if the viewport height is equal to the document height.
Setting that the touchmove on is ignored on the Crafty element and not on the whole page, so that the webpage is still functional.

There should properly be something like this, but is should be optional and thought through, which this is not.
