Devtools registration happens too early

can-debug/can-debug.js

Lines 30 to 39 in a4ff993

	if (window.__CANJS_DEVTOOLS__) {
	window.__CANJS_DEVTOOLS__.register({
	Symbol: canSymbol,
	Reflect: canReflect,
	queues: canQueues,
	getGraph: namespace.debug.getGraph,
	formatGraph: namespace.debug.formatGraph,
	mergeDeep: mergeDeep
	});
	}

If this happens synchronously, it happens before devtools injects the script that sets up window.__CANJS_DEVTOOLS__.

This isn't a problem with apps using Steal, but bundled apps or apps using Webpack fail to register with devtools.

The fix I put in doesn't actually set the ___CANJS_DEVTOOLS__ global. Going to fix this again.
