Added all of the necessary JS code to add and remove guests

This included a significant amount of coffeescript "boilerplate"
as well as an overhaul of the controllers to use view models.
These view models can use some additional love in the near future,
but for now they serve as a decent enough abstraction for containing
rendering logic; especially for consistent data representations.

Implementing confirm functionality, still needs work

Halfway to implementing confirm functionality, currently the server
call is erroring but the UI mechanics are almost working as expected.
Finished confirm functionality (w/o error checking)

Still need to change the UI in some manner so that it's both prettier and more user friendly.
