BugFix

Fixes a bug when, sometimes, the cursor did not get hidden when playing.
This is because a css property that I couldn't find any reason for it to
be there, so I removed without any problem, that I know of.

Also fixes a path in player.html, loader.gif.
Add text-shadow to captions

Added a shadow to improve visibility of subtitles on white scenes.
