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.

This is all the visual changes - the actual wiring of the UI to the right places is for another PR (though this PR still works independently).
The help icon is known to be weird here - it's a bug in the svg we have. The tooltip also goes right instead of up because making the tooltip go up is not easy work for this PR - maybe a future one if we *really* want it to go up.
These icons are based on Feather as the original source, but they have various
tweaks applied, such as stroke width, color, etc. Hopefully the tweaked name
makes this more obvious in the future.
