rubidium c973bd87ce (svn r12868) [0.6] -Backport from trunk r12795, r12776, r12683, r12681, r12678: 
- Fix: Vehicles could break down during loading and keep loading. The intention of the break down code is not to break down when having zero speed, therefor break downs now do not happen when loading [FS#1938] (r12795)
- Fix: [OSX] In some rare cases when using an uncalibrated monitor the system colour space could not be retrieved. Show an error when this happens instead of just trying an assertion (r12776)
- Fix: In some cases a news messages would not be shown [FS#1906] (r12683)
- Fix: When a road vehicle has a tram only stop multiple times in a row in it's orders, only the first one would be skipped [FS#1918] (r12678)

*
* 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
* \endverbatim
