BugFix: Unreal Engine 4.10 Third Person Tutorial.

I've really been enjoying Unreal Engine and the Learning resources they provide.  Unfortunately the Engine is constantly updating and sometimes methods explained in these tutorials can change.  In this case Introduction to Third Person Blueprint Game has a couple issues(ie Using AnimNotify montage branching messages, branch point tracks, and using the DefaultSlot group for the layered blends).  I updated working solutions to a github repo .  

More information about branch tracking can be found here.
