UpdateScope

• Removed unneeded allow insert on Posts and Comments.
• Renaming postMeta template to postInfo to avoid ambiguity.
• Fixing avatar code.
• Adding update prompt package.
• Upgrading to Meteor 0.9.2.
• Do not remove deleted comments from database, use isDeleted flag instead.
• Now showing "X new posts" instead of just displaying them. Thanks @dburles!
