Changes

tsk20 Adds most read stories to home page
Adds a carousel for the most read stories in the main view along with
the necessary logic to the controller. The carousel is moved to a
separate file to improve the maintenance of this visual component.

fix: Fixes problem with number of characters in search view
If the number of characters in a story is less than 60, the rendering of
the view will fail. Text length check is added.

fix: Fixes NullPointerException problem in most read stories method
The service method did not initialize a variable, which it then
compared, not guaranteed to be non-null.
