Title Casing some but not all dialogs is probably not the way to do this which is why I've added a UI audit to the trello board.  I don't think any of the dialogs in project manager use title case for the titles so I vote for leaving this as-is for now.  This change makes the `rename` case different than the `create` case but we should merge those two handlers so we maintain consistent messaging.  There are a few other errors that are not title-case in project manager.  Care to fix them as well in this PR since you're cleaning things up?  "Error Loading Project, etc..."
