Added ability to disable teaser independent of teaser length

I prefer full length articles at all times on blogs and don't like teasers. I added the ability for people to disable teasers so full articles will be shown by default. The teasers can e enabled just like comments from the admin page or trough the normal settings.

However not sure if the post partial now is conform standards. Maybe the helper method "blog_post_teaser" could encapsulate the check which is now done in the view and return the full length article instead of a teaser if the teasers are disabled.
