Added Pastebin and JSFiddle Support, Code Cleanup

Implemented support for Pastebin and JSFiddle.

**Pastebin**
Was planning on using the embed feature of Pastebin but there were problems with the IFrame so I decided to use the raw output instead. The `hashRe` should match the following urls:

    http://pastebin.com/7nAAqYRP
    http://pastebin.com/index/7nAAqYRP
    http://pastebin.com/raw.php?i=7nAAqYRP

**JSFiddle**
JSFiddle uses it's own embed functionality. Someone might need to look at the `hashRe` to clean it a bit up. It should match the following urls:

    http://jsfiddle.net/zalun/NmudS/0/
    http://jsfiddle.net/zalun/NmudS/0
    http://jsfiddle.net/zalun/NmudS/
    http://jsfiddle.net/zalun/NmudS
    http://jsfiddle.net/NmudS/0/
    http://jsfiddle.net/NmudS/0
    http://jsfiddle.net/NmudS/
    http://jsfiddle.net/NmudS

**Site Removals**
Removed the websites `picsarus` and `memefive` since they have been down for quite a while.

**Refactoring**
Some minor refactoring `imageLink -> mediaLink`, `imgDiv -> mediaDiv`

you can't just put it in the optional_permissions section - you have to
request the permissions...

see how tweetexpando works... it's extra work, we might want to have a
reusable "request permissions" function in RES or something although it's
chrome specific, so, I dunno.
