Upgraded Colorbox
Corrected logic as .concat does not work
Used hooks to load up scripts and stylesheet

This will prevent errors when wp_debug is set to true
Added comments.php from twentythirteen

This is required by wp_debug, but it is not used normally as it is
expected that the user will use Disqus or IntenseDebate plugin.
Set the meta descript to the excerpt
