Input and Third Person Controller

Work has slowed down a bit again, so I'm able to get back to the wiki. I need to go through my tutorials and update them for the input system changes and the 3rd person controller changes.

I just want to make sure that everything is done with them (at least the public interfaces).

Yes.  I wrote in the comments that all was done and for people to please test.  This was before we decided to mark issues as fixed.  I'll do so now.
