Initial Commit
most functions are working now. adding urls, deleting and rearranging urls all working. if the user enters a bad url, an alert will pop up to notify them. if they enter a good url, an alert will appear to notify them that the alert has been added. the url will automatically get added to the list and the screen won't change in case the user wants to add more urls. once they are done adding urls, they can swipe back to the table and see the list.

TODO is opening up a web browser for each url in the list.
