Fluidapp Gmail badge + notifications

fluidapp-gmail.js

/**
 * Description: Updates the badge to the unread count.
 *              Scrapes the inbox for new mail every 5 seconds and displays a notification for each new message.
 *              Does not support new messages in a conversation. I.e. 1 row in the inbox = 1 notification.
 *              Only tested on OS X Mountain Lion. This will break when Gmail changes their DOM!
 * 
 * Patterns:
 *   *gmail.com*
 *   *mail.google.com*
 *   *google.com*mail*
