* News system is realized as a FIFO queue (in an array)
* The positions in the queue can't be rearranged, we only access
* the array elements through pointers to the elements. Once the
* array is full, the oldest entry (\a _oldest_news) is being overwritten
* by the newest (\a _latest_news).
*
* \verbatim
* oldest current lastest
* | | |
* [O------------F-------------C---------L ]
* |
* forced
* \endverbatim
*
* Of course by using an array we can have situations like
*
* \verbatim
* [----L O-----F---------C-----------------]
* This is where we have wrapped around the array and have
* (MAX_NEWS - O) + L news items
