styling for title field; correct input target in tests; make download filename safer with default, max length; in playground index, correctly pass props through to gui container

If the VM is ever instantiated, which happens whenever GUI is instantiated due to default props, then IE11 will crash

For some reason the travis eslint did not catch these missing prop validations.

*Kind of*. This isn't a good way to do it because we use the storage singleton before GUI is mounted. This needs to happen differently, like configuring storage in the project loader hoc and passing it down, so it could be attached to the VM once it has a VM?

Fixup 723d975d062ce3b585715b5cbabfcdae218d901a

This reverts commit 723d975d062ce3b585715b5cbabfcdae218d901a.

This allows the project to continue playing/retain state while toggling language or player state.

And implement toggle on player playground

Also include the hash of the project in load errors from the server so we can debug them

scratch-gui exports `index.js` instead of just GUI container.

* Export initial states for each reducer
* combine all gui reducers (excludes scratchPaint and intl)
* combine all initial states to create default guiState for preloading in www
* expect all of the gui state to be accessible at `state.scratchGui`

GUI will export a reducer to be included in the enclosing component’s redux when GUI is used as a library. The app-state-hoc is moved into the playground examples to provide a store when GUI is being used stand-alone.

Fixes #1853

The initial intl store expected an object with an `intl` key, not the intl object as returned by `injectIntl`.

Also changed GUI proptypes to accept Object as well as String for projectData to avoid warnings.

- export image and sounds in dist/static/assets
- rename main export (`scratch-gui.js`, not `index.js`)
- move project-loader-hoc back to lib (VM doesn’t load properly without it)

It seems like there is some kind of touch action interference coming
from the blocks panel, where if you touch the tabs on a touchscreen
chromebook/chrome responsive mode, it does not select the tab if the
touch radius is overlapping the blocks panel at all. See gifs in PR for
more explanation. Fixes issue #1283, making chromebooks useable!
