@nilshedstrom Thanks! They all look great, except for "config", which is difficult to see on default dark theme:

and is a different size than the others:

Did this icon come from a different place? Thx.

There is another settings.svg in Azure Icons which is gray but that one did not work with vscode for some reason (displayed as a single pixel).
I changed the icon to the one for Application Configuration which has mor colour and does not look like the parameters icon.

I do not see how my change caused the test TLE colorization array-access.INVALID.json to fail on the Windows build (but passed on Linux and Mac). It seems like it failed on the 2019-12-03 too.

I added an icon for functions (which should solve issue #421).
Refactored the existing icon tests to one (should be a bit faster).
Added tests for function icons.

Perfect, thanks again!
