fix apiref CSS: overflowing text

In Firefox, when zoomed, some text overflows inside a floated container
and is clipped (this also happens in Firefox when the font of code is
changed).

This commit removes the floating, since for a single child element it doesn't
make sense anyway to be floated.

docs: Implemented routing for the playground.

Now the playground page of the website handles routing to navigate through samples, which means that each sample has its own URL, and loading this URL will show the sample. History is supported as well.

flatiron/director (https://github.com/flatiron/director) is used to handle this routing.
