CAS-1425: aligned view names to match the jsp filename

Some view names in default_views.properties have been updated to match the file names of the jsp's. The respective view names in the login-webflow.xml have been updated as well. This pull fixes https://github.com/Jasig/cas/issues/490
@leleuj, you are correct that this bring together a view's jsp filename with the viewname referenced in the login-webflow.xml. As for customized JSP pages, it shouldn't change anything if the filenames where kept the same. 

(Although I've seen some implementors that give the jsp file a unique name and update the `default_view.properties` be commenting out the default and putting in a replacement. *sigh*)
