Added a way to fetch all people from trogdir...

...that are currently in the db and refresh their attributes with the ones that are current in trogdir. Does not affect sync status or remaining syncs
At the moment nowhere. I created it so that I can use it in console if errors occured on sync although in the future as developers we will likely have the ability to fetch people on the people index view or somewhere like that. 

I am going to add something to this pull request so don't merge it yet.
