Some Enhancements

Hi,

I'm new to Github and jquery and wanted to share some enhancements I made - not sure if you would like to include them:

1. added ability to define different window sizes for each icon's popup window.
2. when using email, the popup window would remain open - enhanced to close it by allow you to set the class to nopop or pop.
3. changed twitter to use the Twitter Web Intents and added via as a value that can be included. This does require the twitter widgest.js be included in the html.
4. changed facebook to use the feed dialog (looks nicer). This does require the facebook sdk to be included in the html.

Following is the new script. Feel free to use my changes if you want.
