import css for Growl Notifications
[BUG] This fixes issue #11. When no options are specified in the ember-cli project's brocfile.js, then the options object will be undefined. So ensure that the options object exists before looking for its components or import properties.
Set options to {} if undefined (this will occur if the user doesn't specify any ember-cli-bootstrap options in their app
Restored original formatting for code consistency
