I forgot that the integration test needs to try clicking, because finding text will find invisible text as well

This was causing a re-render for anything using the `drop-area-hoc`

Set up cloud provider and attach it to the VM. Obtain information about cloud host and username from props.

And start just creating assets to hand to the VM. Towards https://github.com/LLK/scratch-vm/issues/1577

* Connection Modal loads its own data

* Connection does not update flyout status buttons

* WIP moving connection modal into redux

* Lint fix and remove unused prop

* Close modal even if exception on disconnect

don’t let `react-tooltip` decide on placement for the action menus. Force left or right depending on language  and the location. (It turned out there were other places it overlapped, the sprite selector was just the most obvious)

This is taking advantage of the fact that react-intl can support nested IntlProviders. GUI will use it’s own ConnectedIntlProvider, that maintains the translations in redux, while www will continue to have it’s own IntlProvider that is initialized when the page loads.

Moving the IntlProvider into GUI meant that nothing in the playground can use injectIntl, so the default project name needed to move into the component instead of being in the reducer.

The Localization HOC is added, it takes an optional onSetLanguage handler, so www can pass a function that will set the cookie that www needs.
