- maintain the UIView root when a page is being rebuilt
- hopefully removed a weird race condition when a page is being shown
- removed some random memory leaks
- prevent release cycle when registering self as outcomeListener
- allow users to install their own viewManager
- remove activity indicator, even when it's shown in a different window (i.e. when an alert is showing)
