added routes and views for dashboard, playerview, navigation

Added routes and views for:
-admin dashboard
-single player of a group

added view for the sign in/sign up text which is inserted into the '.nav-container' in the HTML when the router is created. it should be made to change depending on if there is already a user logged in.

removed the login route, but kept its view to be used later as a modal overlay, pending client approval.
