Android9

What happened in this pull request:

1) I expanded the Android API routes to include the ability to send via XML and JSON a list of appointments to the Android application client.  In future upgrades, this capability will allow Android to show a(n editable) list view of a client's appointments.  This will soon allow the Android device to fully mirror the web app's capabilities.

2) Removed superfluous code that printed easily-identifiable lines to the Rails console.  These lines helped me identify key components of JSON objects and HTTP requests, and are no longer necessary.

3)  Added [jQuery-UI](http://www.jqueryui.com/) for more pleasing visual effects.
>EDIT: Fixed order of loading JS files

4)  Added animation and JavaScript-based dialogue confirmation when deleting appointments from the index view.  The current animation reduces the `height` property of the `div` element clicked on and then fades it off the DOM.  After the animation, the remaining appointments in the list slide upwards and stay aligned with the top of the page (just below the 'Add Appointment' button).

5)  Added `/db/seeds.rb` to the `.gitignore` file.  Should the app roll out live, I will be able to add the correct (and private) information about the employees of Hair Etc... without fear that their personal information will be made public.
