The separate pause and play buttons necessitated changing between them
to signal that state had changed. Replacing it with a combined
pause/play button sidesteps all the issues in syncing up when which icon
should be shown.
The old QML was a giant mess of implementation details and logic.
Reducing the buttons to only 2 essential properties allows the
MediaControllerKeys object to be more easily understood.
Moving the MediaControllerKeys into its own QML file allows the
resulting page to be more easily understood and individual pieces
swapped in and out.
The current QML directory structure is non-existent, breaking parts down
into cohesive folders will allow for easier understanding of the bigger
picture.
.pngs were chosen because the .svgs were only available in black. Qt
currently does not have an easy way of changing colors. The rest of the
interface icons are white, so getting them in white was necessary.
