Building out the content manager

Just a quick post today. Just building out the content manager, so just pretty straightforward coding. Created a display template (which amounts to a special partial view) for dates so that the time part is omitted. I also needed to solve a problem were line breaks weren't being shown on multiline text. This was resolved with a simple replace call, but probably could be done more elegantly with a display template. Earlier on, fixed a few niggles with the calendar app, such as the selected date resetting when going to the about screen or keyword detail screen. Did some general tidying of these screens.
