LibJS: Use OrderedHashMap for the Shape property table

Browse source 
This allows us to get rid of property_table_ordered() which was a
heavy-handed way of iterating properties in insertion order by first
copying them to a sorted Vector.

Clients can now simply iterate property_table() directly.

3% speed-up on Kraken/ai-astar.js :^)
