Pass options into init function

Hi there!  Great plugin.  First pull request and learning javascript!

When initializing the plugin and passing in options 
$('#panel').codebomber_Panel(options = {orientation: "right"});
I was not able to override the default behavior (orientation left) unless 
I passed the options object to the base.init() function. 
As is, I was getting undefined when logging options to console with in the init function.

Let me know what you think or if I missed something in the way I was trying to pass
in the options.
