Textualize/textual v0.3.0

Scarily good release with FR units

on GitHub

A number of fixes, and internal enhancements.

We have a new API for running textual apps asynchronously, and a much better way of running integration tests. Testing is important and we will be documenting this in a future release.

Also in this release, we've made fr units more useful. These CSS units can be used to easily create flexible layouts. See the video below:
