Rename for stack-clearing post spec run to be more clear; use the real setTimeout when clearing stack
Test asynchronous parts of Jasmine asynchronously
Merge the node performance suite into the node suite

The node performance suite can be run with node: `node
spec/node_suite.js --perf`
Have QueueRunner run specs iteratively if possible, fallback to recursion for async specs

This prevents the stack from growing as large for the normal cases and is giving a significant speedup for the performance suite
