* convert all tags to have a `tag` field corresponding to the query parameter, and `intlLabel` field that defines the title message for `FormattedMessage`
* define all the tag messages in a shared file so they can be included in multiple places.
* convert the `TagButton` to use `tag` for the `onclick` handler value, and localize `intlLabel` for the title.

In the library I’ve continued to use `tag.toLowercase()` even though all the tags are currently defined as lowercase. It’s safer, but currently not strictly needed.

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

fixes #2983

- empty MapDispatchToProps (dispatch)
- remove `on…` VM listeners from props passed to wrapped component.

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?

This reverts commit 723d975d062ce3b585715b5cbabfcdae218d901a.

Also just cleaner formatting of the connect in the `errorBoundary` container

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.

* Delete confirmation i18n

* Update so that it works

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

* Add hideIntro prop to GUI

* Move intro modal hiding logic into its own function

* 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.
