Revert "Another refactor of the setFilter method to stop it firing un needed "add" events"

This reverts commit 459701b876fe44661097b27246c25f97a8337e78.
move router up to top of directory, since there's only one of them
remove unused initialize() method in IssueModalView
move view logic from the router to the MainView
big refactoring of app.Router - closes #41

completely changes how modals are instantiated and how the navigation is
done.  basically, the modals no longer need to be aware of navigation -
they just inform the parent view that they are closing, and navigation
happens at a higher level.
clean up modals when they're closed, and fix closing of welcome modal not always navigate to /
fix overlap ordering of welcome modal when displayed with an issue modal
made common render() method on ModalView
rearrange Router
removed unnecessary bind statement
Merge branch 'complete' of github.com:backstopmedia/hubbub into complete
