Tweaks and small additions.
Merge branch 'development' of git://github.com/jonutter/kuality-coeus into development
Decided to go a different way with updating credit split amounts.
First attempt at credit split update methods at the Key Person Data Object level.  These are, as yet, untested, and we will probably still need a method in the ProposalDevelopmentObject that will update all the splits with values that won't cause the Proposal to throw an error.
Fixed the problem with key persons and units in the create method for key personnel.
