Disabled $location.replace(); this allows the user to slam the back button and actually trace back their steps. Since I use ngRoute, this is perfectly safe and doesn't break the app. Hoorah for good design!

Removed an invisible tag related to post deletion; will bring back if needed to implement post deletion

removed a vestigial divider tag

minor style tweak
added a 'clickable' class to style.css, for tags that use ng-click to display an appropriate cursor, to signify they're actionable

strictly a UI update
