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

* 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.

fixes #1579 

[DEVELOP] Update dependencies for translations

Instrument device connection events

* Update scratch-blocks
* Update scratch-l10n

Share costumes and sounds to stage

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.

Update scratch-paint to the latest version 

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).

Add direction popover with dial and rotation style changing

Turbo mode menu 

Update scratch-vm to the latest version 

Move listeners up to vmListenerHOC, and add listeners for new turbo mode events from scratch-vm#1413

Bring in hotfix to beta stuff to develop

Expected change for a className that uses classNames function now, but didn’t before.

Changed left/right to first/last. Added direction aware styles.

Correct margins for tabs, tab icons.

Checked with Moran, and the sound waveform along with play button should stay LTR. So added a `row-reverse` that only applies when `dir=“rtl”`

Move the margin to the other side.

Rename buttons first and last instead of left/right. Add RTL styles.

This bled into normalizing z-indices for the action menus in the z-index.css. The tooltip id was not unique between action menus for ‘suprise’ and ‘paint’, so `mainTooltipId` was used as a prefix to make them unique.
