Checkboxes and Radios as buttons !!Plus More!!

Also update dropdown name space and have dropdowns use a `data-` instead of flipping a class on an element.

Also remove parent folders from rolodex modules. The modules are too small to need their own directory. If they need their own directories (perhaps to store documentation/readmes etc) then they can be put in when needed.

Used to be:

```
|--rolodex_angular/
|---- src/
|------ buttons/
|-------- buttons.coffee
|------ modal/
|-------- modal.coffee
```

Now it is:
```
|--rolodex_angular/
|---- src/
|------ buttons.coffee
|------ modal.coffee
```
