When swapping video and presentation now the presentation is updated
properly, before it would not show any slide until there was a slide
change.

Also added a few protections to prevent js code from breaking.

When pan/zoom was done, the image would zoom and move inside the svg, that
occupied a larger area than the viewbox we wanted to show.

Had to control the size of the container that has the svg via javascript,
to make it exactly the size we want to display the presentations and with
this crop all parts of the presentation that lie outside the container.

Small changes in text formatting and positioning.

The cursor was being moved to the right more than it should when the
sidebar was opened.

And some small improvements in the thumbnails.

Wasn't being shown after the page was made responsive. Now it shows up
in the correct place and disappears when not necessary.

Now it keeps playing if it was playing before and shows the current slide
properly.

Now it's done in the application and positioning is not hard-coded
inside acorn player, so it works in a responsive page.

Still not 100%, the playback jumps back and pauses on swap. Have to
make the transition seamless.

Includes a custom theme for acorn media player.
Uses the Foundation framework, version 5.5.3
