Fixed links being added to links table incorrectly.
Added the info option.

The info option allows you to get any information on a url that was stored in the meta table.

For example:
cosa -I http://www.example.com/image.jpg
would output:
http://www.example.com/image.jpg
dimension-x: 800
dimension-y: 600

Currently the only items being added to the meta table are images, and the only information
being stored are width and height.
Removed unnecessary parameters, added support for info option.
