Improved CoffeeScipt error reporting

When there is a compilation error, it now throws this and restarts the server:
```
error: CoffeeScript compilation failed:
error: SyntaxError: unexpected )
error: In file: /assets/js/views/app.coffee
error: On line: 13
error:   initialize: () -
error:                ^
```
The current behavior after a compilation error is to keep restarting the server (if your using forever) and displaying this error.
