Don’t intialize cards position in reducer - position needs to be set based on isRtl.

Rename prev/next icons to right/left arrows

Make `NextPrevButtons` function RTL aware so that it puts the prev/next on the left or right based on the direction of the language.

Note: the coming soon tooltip positions are calculated by react-tooltip, and they do not handle RTL.

* Delete confirmation i18n

* Update so that it works

padding and margin changes to make www project page layout work without hacks; hack to position monitors correctly

* Don't show intro modal if hideIntro passed to PreviewModal

* Add hideIntro prop to GUI

* Move intro modal hiding logic into its own function

Since the mainTooltpId is now being used as part of the action menu items, make sure it is generated in the constructor of the action menu component instead of within the render method. This fixes a regression caused by a recent change where the file upload buttons in the action menu stopped working.

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

added a line to manu-bar css so as to prevent brokenness in nav bar in Japanese and Chinese languages.

* 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.

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).
