(feat) Add basic create_campaign HTML, controller, and services.

In the future, for Angular factories, return a `components` object.

## Example:
#### Instead of:
```
var signup = function() {};
var login = function() {};
return {
  signup: signup,
  login: login
};
```

#### Do:
```
var components = {};

components.signup = function() {};
components.login = function() {};

return components;
```

## Why?
Saves time because you don't have to retype the names 3+ times.
