Creates an Edit mode and styles links

I copied the ViewBookmarksController into EditBookmarksController.  I then removed the unneeded portions from the view controller. I did the same with the editBookmarks.jsp/viewBookmarks.jsp and moved some shared dependencies to include.jsp.  I added the edit forms to the bookmarksPortletContext.xml.

I didn't go through and update the code I was moving around, so I can say that it's working and the same code as before, but I can't say it's been newly touched.  Maybe work for a round 2?
