#24 2.2.9 tree view | Exec order incorrect

[colin froggatt]

When displaying the target execution order for a target
with > 9 dependancies, the order is incorrect. It is
sorting the number alphebetically rather than
numerically
i.e. for 12 dependants, the order is displayed as :
1, 10, 11, 12, 2, 3, .... 8, 9.
it should be :
1, 2, 3,4, 5 .....9 , 10, 11, 12
