We don't need columns of divs to equally size themselves, so use easier layout techniques to make the list fit in the container. We have to take a hit with `height:100%`, but the hit is much more insignificant than confusing the layout engine.
The layout engine has a hard time with dynamically-but-statically-sized stuff like `width: 100%; display: flex;`, particularly when it is nested so badly. Overall this should improve performance for the app by not having to re-paint so often.

It's become obvious that these random floating points everywhere
are unwieldy. Now they're all in one place with some fairly logical
variable names which will help out in design->implementation phase.
Font size of the whole app would ideally be controlled by a single
value. This value is currently hard coded using the :root CSS selector.
It is the intention to make this value configurable within riot. In the
interim all font-sizes have been converted to rem by the simple process
of regex. Replacing px values with their equivalent rem values assuming
a font size of 15px and then rounded to three decimal places, which was
the base at the time of this transformation.
I'm expecting another commit cleaning up rem values but I thought it
best to leave that to review.
This commit doesn't address any scaling issues. I thought it better to
land this unwieldy, mechanical, invisible change before the others
otherwise the pr would be impossible to review thoroughly.
