[Plugin: SoundCloud Shortcode] Whitespace before URL causes error

If whitespace is left between the opening soundcloud tag and the url the widget fails to load.

ex:
[soundcloud] http://soundcloud.com/talenthouse/blood-on-the-dancefloor[/soundcloud]

This is a very easy mistake I am sure my writers will make.
