Added message to the delete
-The message lets the user know that his/her action was successful
Removed url addition and replaced with reverse function to properly escape characters
Changed delete comment to use "delete()" instead of "is_removed=True"
-If a comment is set to "is_removed=True" and a new one with the same contents is added, it will not show up in person.html
Merge pull request #37 from daveeloo/post_delete
