Dave Davenport 7929818be2 Change how DRUN history is implemented to fix: #579 
- This solution will correctly obey all priority rules as set in desktop
files.
- history only affects the application being sorted at top, not affects
what desktop files refers to this.

Possible issue is speed of this solution, it adds a sorting. (hopefully
limited, as only history items need to be moved).
and several lookups through the whole list of applications.
This needs some profiling to see if it becomes an issue, several
solutions can be applied to make this faster again.
O(history_length*num_netries)+complexity(qsort)

Fixes: #579
