Add daily reputation cap

edit

This is crucial for a reputation system that from a certain point allows you to edit other peoples contributions.

Perhaps certain editing operations should require multiple non-admin users to vote on before executing. (Of course admins would still not be limited like mere mortals. ;-)

This system could still be "gamed" if admins were on vacation, but unlikely if thresholds are set appropriately. The only way to truly prevent rigging of the vote is to compute how much karma is based on group reciprocity (more of a zero-sum computation, similar to Google PageRank.)
