Add local caching for MapDefinitions

[GregHib]

Remove GameObjectArrayMap in favour of GameObjectHashMap
For normal/low mem mode:

• 500ms/120ms slower on first start
• 250ms/275ms faster on subsequent starts
• 105mb/0mb reduction in ram usage
• 52mb/26mb increased disk usage
• Minimal performance impact as object data isn't read frequently.
