property browser: respect property ordering

Consider the following situation:

Property Name     Property Order Index
-------------     --------------------
propA4                   4
propB5                   5
propB4                   4

And the loop goes over these properties in this order.
propB4 should be before propB5, but with the old code,
propB4 would be pushed after propB5: it asks for position
4, but as positions 4 and 5 are already occupied, it gets
pushed to position 6.

Remaining difficulty: properties from different
property index ordering series will be interleaved.
This should be solved at object model level;
ideally property order index should be unique,
at least within an object.
