* This function refreshes the job list. It queries the server for the required
* information and then updates the list control.
*
* \par Notes on the implementation of RefreshList()
* For efficiency reasons, after the initial refresh, all refreshes are
* incremental. Because IPC is the slowest part of the whole program the client
* only gathers the only the information that is subject to have changed from
* the server. The list control is also left alone during the process so that
* it is greyed out for as short a period as possible.
*
* \par
* The list control is also updated incrementally, yet for a completely
* different reason. Whenever the list control is cleared entirely, it not only
* takes time to reload the entire list, but it resets the current position of
* the list in the scroller, so every time the client refreshes the user is
* looking at the top (and most likely irrelevant) portion of the queue again.
*
* \par
* Due to the incremental nature of this code, it is rather complicated and
* should be left alone, unless there is a good reason to change it.
