Handle RTL for the Modal Component (and things that used the modal component)

Fixes #2756

The ‘back/retry’ button in the connection modal should be reversed, but the others (bluetooth icon, question mark) probably shouldn’t.

build dist, even when run without NODE_ENV=production

Add from backpack to sprite/stage tiles

* center the title on full screen modals.
Adding the `[dir=“ltr”]` atttribute to the css rule for a child style didn’t work the way I expected.
`[dir="ltr"] .full-screen .header-item-title` did not match the fullscreen title element, so the style wasn’t applied.
`.full-screen [dir="ltr"] .header-item-title` did match.
* fix the filter to reverse the icon and ‘x’ in the filter input
* more space after the library back icon
* reverse the arrow on camera -retake image and rerecord sound.

Fixes #2756 Libraries and many other modals share the Modal Component.

Connected the Modal container to redux to make it aware of the RTL state, and then made sure that all places that use the modal component import the container, not the component directly.

Update scratch-blocks to the latest version 

Two reasons: 
1. Avoid triggering "connected" event, because the device was already connected
2. It is not good to call `setState` in componentDidMount, which is effectively what it was doing.

I think this switches all the icons we saw. I also switched the icons on the tabs (the blocks going the wrong way looked bad).
