Add an ObjectDB Profiling Tool

Browse source 
A new tab is added to the debugger that can help profile a game's memory usage.

Specifically, this lets you save a snapshot of all the objects in a running
game's ObjectDB to disk. It then lets you view the snapshot and diff two
snapshots against each other. This is meant to work similarly to Chrome's
heap snapshot tool or Unity's memory profiler.
