Improve StackAnalyses view by adding more information

[ljelinkova]

At the moment, the Stack Analyses view has only 3 states

• empty
• loading
• displaying stack analyses

Instead of empty view there should be information how you can run analyses or some button to run analyses over the whole workspace on one click. Also, when analyses is aborted by timeout or an exception occurs, the view should display some message.

This is no longer necessary as crowd sourcing api will be called as soon as the manfest files are sent to recommneder api.
