Access to Memory (AtoM)

The following minor enhancement has been provided by community user Matt Innes (minnes-archives) as a pull request to the public AtoM project.

Currently, we hard-code the size of the mediaElement media player to 320x240. This leaves the player using far less than the available real-estate on the page, and also prevents the size of the player from adapting responsively based on the available device / screen width.

This issue will instead set the player to use a relative size (style="max-width:100%;"), that will adapt responsively based on the available space of the main body on the view page of a description. A comparison of the new and the previous results has been attached for reference.
