choose placement of rating and average info widget - in teaset and in node, or in node only

Issue Summary

Hi

Can you pls add option for placement of rating widgets in teaser/full node?
my idea is:

- rating widgets in teaser and full node
- rating widgets in full node only

e.g. option I like the most is to have in teaser just average rating info, and in full node to have rating option + average info.

thanks
Igor
