Testing the new insta command

For easily embedding an Instragram photo.

Use the URL to the web page and not the image:

<img src="http://photos-d.ak.instagram.com/hphotos-ak-xfa1/10684334_1534205166796627_1819483882_n.jpg" width="320" height="320"></img>

1. will do a fetch on that URL
2. parse the web page for the Open Graph meta property:
   <meta property="og:image" content="http://photos-d.ak.instagram.com/hphotos-ak-xfa1/10684334_1534205166796627_1819483882_n.jpg" />
3. use the content URL within an HTML img tag with width and height set to 320 pixels. I use 320 pixels the most when embedding an Instagram photo, so I'll default to that.
4. maybe provide the option to specify width and height params. Instagram photos are normally 640 x 640 pixels. maybe allow:
   <img src="http://photos-d.ak.instagram.com/hphotos-ak-xfa1/10684334_1534205166796627_1819483882_n.jpg" width="320" height="320"></img> 640x640
