Added logout features and corrected the views to use the controller action
routing function.

Corrected other routing features where already implemented.  Most
'finalish' routing should be using the Redirect::action function.

Created the login page for use as the intermediate when attempting to
access auth-required resources.  Once authenticated on this page, it will
attempt to redirect to the intended URL, or return to the recent.feed
page.
Updated navigation menu to use bootstrap and also link to the respective
feed controller action.

Updated relevant views and added the listItem view which is for a single
message.  Updated index to use this view now.

Updated routes to reflect these changes where needed.
Updated LikeController to handle the store command.

Updated the listItem view to include markup allowing for the 'like'
button.

Updated index file to use the listItem view.

Updated the post view to use URL::action for the form action.
