* Fix action-bar systemIcon
Fix CSS applying
* refactoring
* fix console
* remove StyleScope import - it is private and cannot be imported in public .d.ts
This implements the option to have http.request() not follow server's 3xx redirection replies
but instead return the exact redirection code and headers.
* on iOS, it uses a different NSURLSession instance for non-following request,
with a NSURLSessionTaskDelegate implementing URLSessinTaskWillPerformHTTPRedirection...
* on Android, it just passes the option on to org.nativescript.widgets.Async.Http;
so this requires the respective commit in tns-core-modules-widgets to work
