Docs: delete empty readme.md's

Documentation is now centralized on the wiki.

Refs #121
Merge branch 'refs/heads/horiz-scrolling' into develop
New Build
Fixed: page now loads with initial padding
Fixed: a number disappeared

And now it has appeared once more.
Fixed: plugin Icon classes hardcoded

I was going to replace the class name filter with one based on the parent, but it seems that it is no longer needed to filter elements to enable events to pass through the jQuery.kinetic element. Tested on iPad, and tapping canvas and download icons works without the filterTarget code.

Fixes #200
Fixed: Re-instate top/left of viewport calculations

At least temporarily we'll leave the jQuery version in place.
