Doesn't work with Require.js

The bower distributed delorean does not work with Require.js

First problem is `require('events').EventEmitter`:

```
module.exports = requirements = {
// DeLorean uses **Node.js native EventEmitter** for event emittion
EventEmitter: require('events').EventEmitter,
// and **es6-promise** for Deferred object management.
Promise: require('es6-promise').Promise
};
```

But the module is defined as:

```
module.exports = EventEmitter
```

So I think in the injector it should just be `require('event')` right?

Second problem is in the injector:

```
// This library needs to work for Browserify and also standalone.
// If DeLorean is defined, it means it's called from the browser, not
// the browserify.
if (typeof DeLorean !== 'undefined') {
for (var requirement in requirements) {
DeLorean.Flux.define(requirement, requirements[requirement]);
}
}
```

But when used in the browser with Require.js, DeLorean _is_ `undefined` because:

```
if (typeof define === 'function' && define.amd) {
define([], function () {
return DeLorean;
});
} else {
window.DeLorean = DeLorean;
}
```
