Feed information

Today I added a small feature to the service. When you are done creating your custom feed, the page gives you more information about the feed you just created. It tells you the reading rate and the date you will finish. For those who created a feed to finish on a particular date, it will tell you the average number of minutes it will give you each day. For those who created a feed based on a number of chapters each day, it will tell you when you will finish.
