Title: Predecessor does not *always* have an Heir

I made some changes based on the requirements of a current project:
1) That the acts_as_heir_of may be passed a symbol that needs to be converted to camel case (e.g. FeedbackNode), so I used the fork from 'davidkovaccs' which had already included a fix for this
2) I did a small fix on signatures for David's change
3) The acts_as_predecessor now does not *always* assume that there is an heir.
