Add new line after seeds.rb when appending

[RoopeHakulinen]

I ran to a problem while adding bcms_news after bcms_event to my BrowserCMS-project. The seeds.rb appendings go to same line and that gives an error while trying to run rake db:install. There is no issue if you don't add any other modules that append this file after bcms_event.

Unlike other modules, bcms_event didn't seem to add new line (\n) after

load File.expand_path('../bcms_news.seeds.rb', __FILE__)

so I added it there. Other modules I am referring to are
bcms_news (https://github.com/browsermedia/bcms_news/blob/master/lib/generators/bcms_news/install/install_generator.rb)
and bcms_feeds (https://github.com/browsermedia/bcms_feeds/blob/master/lib/generators/bcms_bmedia_feeds/install/install_generator.rb).

This is my first pull request ever, so if there is something I could have done different or better, please let me know.
