Extend docs for @InjectViewModel vs. @Inject for CDI/Guice projects

[manuel-mauky]

There are some questions that may be not documented well enough when it comes to the @InjectViewModel annotation.

• Can you use @Inject instead of @InjectViewModel to get the viewModel instance?
  • Answer: No you can't, more specificially: You shouldn't because they aren't identical
• What is the difference? What is done when @InjectViewModel is used?
  • you can only inject the correct ViewModel for the View type, with @Inject you could inject ViewModels of other types
  • ResourceBundles can be injected into the ViewModel only when @InjectViewModel is used
  • existing ViewModel instances can be used when loading a View. This VM instance couldn't be injected with CDI/Guice
• Can you use @Inject for other dependencies in the View or ViewModel?
  • yes you can: Both the View and the ViewModel are taken from the DI container and therefore are managed by the DI container

We should describe these Q&A stuff in the wiki documentation. Additionally we should describe the internal Steps when a view is loaded so that the user can better understand what is happening.
