Removed compulsory vestigial `onViewCreated`,
now it will be created if and only if required
by the @OnCreate annotation.

In case the `onViewCreated` is already in use,
move @OnCreate target to `onActivityCreated`,
In case the `onActivityCreated` is already in use,
move ... to `onStart`.
Improved support for support.v4 Loaders

Mitigated collision course with `@OnCreate`.

Fixed bad check if LoaderCallback is implemented.

Added examples.
