When running with the latest cadquery from pip and the latest cq-editor from git, I get the following error: `Exception: Invalid font prefix "fa"` qtawesome has removed the "fa" prefix for fontawesome 4 in favor of fa5 or fa6, see here: [https://github.com/spyder-ide/qtawesome/issues/279](https://github.com/spyder-ide/qtawesome/issues/279) Replacing "fa" with "fa5" or "fa6" using grep/sed is not enough to fix this. It looks like most of the icon names have changed.
