Grab image description for Pinterest. Extending functionality of "Pinterest Image Pin" Wordpress plugin... http://wordpress.org/extend/plugins/pinterest-image-pin/

grab_image_description_pinterest

/* Now wrapped in an if statement, checking for information to tag onto url even exists in current dom. 
It also now encodes parentheses. 
It was failing silently on some pages and wasn't sure why but it's fixed now. 
I think the pinterest plugin uses multiple links and so I'm only targeting the .pin-it-button class link specfcally now.
I also chained a bunch of .txt stripping (.replace()) events together */

	//Strips unnecessary spaces and tosses any carriage returns, converts to one line//replace parentheses

	//encode colons and adds back a space after colon
