Bugfix - Regression: PR #445 caused a blank screen on startup

[bryphe]

Issue: For apps that don't have an animation or initial event to trigger a dirty window, the screen will be blank until something triggers a dirty state.

Defect: Previously, before #445 , we had a needsRender value on the app instance that was set to true on startup, and anytime an action was dispatched against our ad-hoc state management. When that was removed, if nothing triggered a dirty event, a render would never be triggered.

Fix: Always render the first frame. Bring back a limited version of needsRender in the form of isFirstRender
