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.

- Auditing color CSS and componet CSS to make consistent.
- Made a first pass of changes to increase contrast to elements that previously were problematic

* Implement GH-830: Add coming soon tooltips

This implements coming soon tooltips for:
* the small stage size
* save, load and language

It also creates the component that can be copied over into the paint editor for use there as well.

Lastly, this does a small refactor on the full screen implementation to include multiple small screen sizes too.
